Best Answer Explained in Below-:

The phrase "call for" in the context of the question implies a strong request or demand for something, typically an explanation or a clarification of a situation. When someone "calls for" something, they are expressing urgency or necessity, indicating that the matter requires attention or resolution.

In this case, "demand" (Option A) is the most fitting definition of "call for" because it suggests an authoritative or insistent request. When you demand an explanation, you are asserting that it is necessary for the other party to provide clarification or reasons for their actions or statements.

Option B, "want," is less forceful and implies a desire rather than a necessity. Option C, "expect," conveys a sense of anticipation but does not carry the insistence of a demand. Option D, "hope," suggests a wishful thinking rather than a firm request. Thus, in this context, "demand" effectively encapsulates the authoritative tone implied by "call for," making it the correct choice.
