Question

5 ____ shirts are beautiful, but those ones are not nice.
options: these, that, those, this

Explanation:

We need to choose a demonstrative pronoun that agrees with the plural noun "shirts" and the context. "These" is used for plural, near - distance objects; "That" and "This" are for singular; "Those" is for plural, far - distance, but here we need a pronoun for the shirts being referred to (likely near in context of the sentence flow). So "These" is the correct choice.

Answer:

A. These
