The correct answer is B. Inconsiderate
Explanation:
In language, the synonym of a word refers to a word that was the same meaning or a similar meaning to another word. In the case of the text presented the word "insensitive" is used to describe John's attitude and this is linked to the word "thoughtless", this means, in this context the word "insensitive" means someone that has no feelings, emotions or does not think about others and therefore, the only word that is a synonym is "inconsiderate" because this is also used to represent someone that does not consider other people or someone that is thoughtless which means it has same meaning as the word "insensitive".
