Spellings

The correct spelling is "Assurance" with 'ss' and 'a' in the middle. Options B and C misspell the vowel sequence, while D combines both errors. The root is 'assure' meaning to guarantee or make certain.

The correct spelling is "Fulfilling" with one 'l' doubled to 'll' before the suffix. Option A incorrectly doubles the first 'l', B omits the necessary double 'l', and C makes both errors. The rule is that final 'l' doubles before -ing suffix.

The correct spelling is "Acquisition" with 's' retained after 'i'. Options A, B, and C all incorrectly omit the 's'. The word comes from Latin 'acquisitio' meaning 'a gaining' - the 's' is essential to its etymology.

The correct spelling is "achievement" with 'ie' after 'ch'. Options A and B incorrectly use 'ei', while D omits the 'e' after 'ch'. The rule here is 'i' before 'e' after 'c' when pronounced like 'ee'.

The correct spelling is "Reimbursement" starting with 'Rei-'. Option A uses 'Ri-', C uses 'Rein-', and D uses 'Rem-'. The prefix 're-' means 'again' combined with 'imburse' meaning to pay back.

The correct spelling is "challenge" with one 'l' doubled. Options A and D incorrectly use 'challange' with wrong vowel, while C omits the necessary second 'l'. The word comes from Old French 'chalonge' meaning 'calumny'.

The correct spelling is "Engagement" with 'age' in the middle. Options B, C, and D all misspell the vowel-consonant sequence. The word comes from 'engage' plus '-ment' suffix, keeping the 'age' sound intact.

The correct spelling is "innumerable" with 'er' at the end. Options B, C, and D all misspell the ending or middle vowels. The prefix 'in-' means 'not', 'numerable' means 'can be counted' - together meaning 'too many to count'.

The correct spelling is "Methodology" with 'do' after 'Me-'. Options A, B, and D all misspell the consonant sequence. The word combines 'method' plus '-ology' (study of), and the 'do' bridge is essential.

The correct spelling is "Cafeteria" with 'te' in the middle. Options A, B, and C all misspell the vowel-consonant sequence. The word comes from Spanish 'cafetería' (from 'café' meaning coffee), and the 'te' is standard in English.

The correct spelling is "Grievance" with 'ie' after 'Gr' and 'ance' ending. Options A, B, and C all misspell the vowel sequence. The word comes from 'grieve' plus '-ance' - the 'ie' must be kept as in the root verb.

The correct spelling is 'sensitivity' with the suffix '-ity' attached to 'sensitive.' Option A uses 'ety' which is incorrect, C is missing the 'i' in the middle, and D has 'e' instead of 'i' in the third syllable.

'Domiciliary' is the correct spelling for a term relating to a home or dwelling. The key is the middle syllable 'cil' - options B, C, and D incorrectly use 'cill' or 'cell'. The stress falls on the second syllable: do-MIC-i-lar-y.

'Assertions' is the correct spelling. The word comes from Latin 'assertio' following the pattern of similar words like 'mention' (not 'mension'). 'Assertons', 'asertions', and 'assartions' are all misspellings with phonetic or transposition errors.

'Overseas' is the correct spelling meaning 'foreign' or 'abroad'. It follows standard English spelling rules. 'Ovarseas', 'Oversaes', and 'Overrseas' contain phonetic errors or double consonant mistakes.
