The word Abandon means to give up completely (a practice or a course of action) or to leave a place, thing, or person, usually forever. It implies desertion or relinquishment. Therefore, the most fitting synonym among the options is Forsake (option B).
When you abandon something, you leave it behind or cease to support it. For example, a ship might be “abandoned” by its crew, or someone might “abandon” a bad habit. “Forsake” carries a similar strong connotation of leaving someone or something, especially a duty, a cause, or a person, often in a way that implies betrayal or neglect. Option A, “Support,” is an antonym, meaning to uphold or assist. Option C, “Protect,” means to keep safe from harm, which is the opposite of abandoning. Option D, “Collect,” means to gather, which is unrelated. Understanding “abandon” and “forsake” helps to describe acts of giving up, desertion, or ceasing involvement, often with significant consequences.
