The correct answer is D. Clear.
Ambiguous means open to more than one interpretation. Auxiliary means providing support or assistance. Responsible means accountable for one’s actions. Salvageable means capable of being saved or recovered.
In the context of the question, the word “ambiguous” is used to describe a statement that can be interpreted in two or more ways. For example, the statement “I’m going to the store” could be interpreted as meaning that the speaker is going to the grocery store, the hardware store, or any other type of store.
The word “clear” is the opposite of ambiguous. A clear statement is one that is easy to understand and interpret. For example, the statement “I’m going to the grocery store” is a clear statement because it specifies exactly where the speaker is going.
The other options, “auxiliary,” “responsible,” and “salvageable,” are not relevant to the question. An auxiliary verb is a verb that helps to form a verb phrase. A responsible person is someone who is accountable for their actions. A salvageable object is an object that can be saved or recovered.
