Choose the word or phrase (A,B,C,D) that best completes the sentence:
Because the first pair of pants did not fit properly, he asked for________.

The correct option to complete the sentence is "another pair."

Explanation:

• "Another pants": This option is grammatically incorrect because "pants" is a plural noun, and "another" is typically used with singular nouns. The singular form would require "another pair of pants."

• "Other pants": This option could be considered grammatically correct in some contexts, but it lacks specificity. "Other pants" implies different pants but doesn't necessarily imply a similar type or a replacement, which is more contextually appropriate in this sentence.

• "The others ones": This option is grammatically incorrect. "Others" is a pronoun that doesn't need the addition of "ones." Also, "the" would be unnecessary unless referring to a specific, previously mentioned set of pants.

• "Another pair": This is the correct choice. "Pair" is singular and correctly refers to one set of pants. "Another pair" clearly indicates he wants a different set of the same kind of item (in this case, pants), which fits the context of the sentence.

So, the complete sentence is: "Because the first pair of pants did not fit properly, he asked for another pair."
