Acoustics is the branch of physics concerned with the study of sound, including its production, transmission, and effects. Astronomy studies celestial objects and space. Histology studies biological tissues. 'Soundology' is not a recognized scientific term.

Bibliophobia is the specific term for the abnormal and persistent fear of books. The prefix 'biblio-' comes from Greek 'biblion' meaning book, and '-phobia' indicates fear. This is a straightforward vocabulary/terminology question testing knowledge of phobias.

The chemical symbol Au comes from the Latin word 'aurum' meaning gold. This is standard chemical nomenclature where symbols are derived from Latin names. Ag is silver (from 'argentum'), which is a common distractor students confuse.

Calcium sulfate (CaSO4) when partially dehydrated forms Plaster of Paris, named after large gypsum deposits near Paris. This is a standard chemistry fact about common compounds and their commercial names. Coaltar is a coal byproduct, Rubidium is an element, and Bruster appears to be a fictional option.

Michael Faraday discovered electromagnetic induction in 1831, which led to the invention of the dynamo. This is a fundamental fact in the history of electricity and magnetism. J.C. Bose worked on radio waves, the Curies studied radioactivity, and Soddy worked on isotopes.

Sharks have zero bones in their bodies - their entire skeleton is made of cartilage, which is a flexible and tough connective tissue. This cartilaginous skeleton makes sharks lighter and more agile swimmers compared to bony fish, and is a defining characteristic of all cartilaginous fish.

Lotfi Zadeh, an Azerbaijani-born American mathematician and computer scientist, first introduced the concept of fuzzy logic in 1965. His groundbreaking paper 'Fuzzy Sets' proposed a mathematical framework for handling reasoning with uncertainty and imprecise information, differing from classical boolean logic.

Fuzzy logic was formally introduced by Lotfi Zadeh in 1965 with his seminal paper 'Fuzzy Sets' published in the journal Information and Control. This places its introduction firmly in the 1960s, making option C the correct answer.

Fuzzy logic sets can return degrees of membership between 0 and 1, not just boolean true/false values. This is the fundamental difference - boolean logic is binary (0 or 1, true or false), while fuzzy logic allows for partial truth values, making the statement in the question false.
