Best Answer Explained in Below-:

The correct answer is A) amoral. A prefix is a group of letters that is added to the beginning of a word to modify its meaning. In the case of “amoral,” the prefix "a-" typically means "without" or "not." Thus, "amoral" can be interpreted as "without morals," indicating a lack of moral consideration or ethical principles.

Let’s examine the other options to further clarify why they do not contain prefixes:

B) "Authentic" does not have a prefix. It comes from the Greek word “authentikos,” meaning "original" or "genuine," without an added prefix altering its base meaning.

C) "Amnesia" features the prefix "a-" as well, but it specifically relates to the lack of memory. However, in the context of philosophical or moral definitions, "amoral" is more commonly recognized.

D) "Aspersions" does not include a prefix; it derives from the Latin "aspersio," which means a sprinkling or scattering and does not utilize any morphological addition at the beginning.

Consequently, "amoral" is the only option that has a clear prefix that changes the fundamental meaning of the word.
