Antonyms

Exhaustive means thorough, complete, or covering all aspects. Incomplete is the direct opposite because it means lacking something or not finished. Note that option B has a typo (Energitic should be Energetic), but it doesn't affect the antonym relationship.

Preen means to dress or groom oneself with excessive care, often to show off. Rumple is the opposite because it means to make something messy or wrinkled. Words like envelop, offend, confine, or antagonize don't capture the neat versus messy contrast.

Expire means to die, come to an end, or cease functioning. Thrive is a good opposite because it means to grow vigorously and flourish. Words like evolve or stabilize don't capture the life/death or growth/decline contrast as well as thrive does.

Testiness means irritability or having a quick temper - being easily annoyed. Patience is the perfect opposite because it means the ability to tolerate delay or annoyance without becoming upset. Words like devotion, methodicalness, caution, or discretion don't convey the temperament contrast.

Profundity means great depth of thought, knowledge, or meaning. Superficiality (the intended meaning of option D) is the opposite because it refers to lack of depth or seriousness. Note that option D is incorrectly written as an adverb (superficially) instead of the noun form that matches profundity.

Squat means short, thick, and dumpy in physique. The opposite physical description is tall and thin, making option B the correct antonym. Options A, C, D, and E describe unrelated qualities.

Dwindle means to gradually diminish or reduce in size or quantity. The opposite is to increase or grow, making option E correct. Options A, B, C, and D are unrelated to the concept of growth versus reduction.

Improbity refers to dishonesty, corruption, or lack of moral integrity. The direct opposite is honesty and probity, making option B correct. Options A, C, D, and E do not represent ethical opposites.

Ire means anger, wrath, or fury. Pleasure represents the opposite emotional state - joy, satisfaction, or delight. While goodwill is also positive, pleasure directly contrasts with the hostile emotion of ire.

Lachrymose means tearful or inclined to weep, often suggesting sadness. Jovial means cheerful and friendly, representing the opposite emotional state. While energetic and rejuvenated are positive, jovial directly contrasts with the melancholy of being lachrymose.

Irksome means annoying or troublesome. Pleasant is the direct opposite, describing something agreeable or enjoyable. While satisfactory is similar, pleasant is the true antonym representing the complete opposite quality.

Itinerant means traveling from place to place, or nomadic. Immobile means unable to move or stationary, representing the direct opposite. The other options (nomadic, roving, wandering) are actually synonyms, not antonyms.

Judicious means having, showing, or done with good judgment or sense. Idiotic means showing a complete lack of judgment or intelligence, making it the opposite. While sensible is a synonym, ignorant (lacking knowledge) is not the true opposite - the opposite refers to poor thinking, not lack of knowledge.

Autocracy is a system of government by one person with absolute power. Democracy is a system where power is vested in the people, making it the direct opposite. Aristocracy is rule by a privileged elite, not the people, so it's not the true antonym.

Lackadaisical means lacking enthusiasm and determination; careless and half-hearted. Energetic means showing or involving great activity or vitality, representing the complete opposite state. The other options (lax, apathetic, slapdash) are actually synonyms.
