I like _ blue T-shirt over there better than _ red one.

Explanation

The correct answer is Option B: the, the.In the sentence I like the blue T-shirt over there better than the red one., both 'the' articles specify that the speaker is referring to particular items that are already known to both the speaker and listener. The definite article 'the' is used when discussing specific objects. In contrast, the other options are incorrect for the following reasons:Option A fails to provide an article for 'blue T-shirt', making it ambiguous.Option C uses 'the' for 'blue T-shirt' but incorrectly uses 'a' for 'red one', suggesting it's a non-specific item.Option D incorrectly suggests a generic reference for 'blue T-shirt' with 'a', while 'the' for 'red one' is accurate but does not fit the context. Therefore, only Option B correctly conveys the intended meaning.
