She looked gorgeous in her new dress.

The correct answer is B. beautiful.

The word “gorgeous” means “extremely beautiful or attractive.” It is a very positive word, and it is used to describe someone or something that is very good-looking. In this case, the speaker is saying that the woman looked very beautiful in her new dress.

The other options are all negative words. The word “ugly” means “not attractive or pleasing to look at.” The word “ordinary” means “not special or unusual.” The word “shabby” means “in poor condition or appearance.” None of these words accurately describe the woman in the speaker’s sentence.

Therefore, the correct answer is B. beautiful.
