CANTANKEROUS

CANTANKEROUS is an adjective that describes someone who is argumentative, quarrelsome, or difficult to deal with. It is often used to describe someone who is constantly involved in disputes or conflicts. Let's break down the given options to understand why option 'A' (Quarrelsome) is the correct answer.

a) Quarrelsome: Quarrelsome is defined as being inclined to argue or engage in conflicts. This perfectly fits the definition of CANTANKEROUS. Someone who is cantankerous is likely to pick fights or arguments frequently.

b) Rash: Rash refers to acting without thinking or being impulsive. Although someone who is cantankerous may also be impulsive, it does not capture the essence of being argumentative or quarrelsome.

c) Disrespectful: While someone who is cantankerous may exhibit disrespectful behavior during arguments or conflicts, being disrespectful is not the primary characteristic of a cantankerous person.

d) Noisy: Noisy refers to making a lot of noise or being loud. Although someone who is cantankerous might raise their voice during arguments, being noisy is not the defining characteristic of a cantankerous person.

Therefore, option 'A' (Quarrelsome) is the most appropriate answer as it aligns with the definition of being argumentative and engaging in conflicts, which is the central theme of being cantankerous.
