Answer:

(a) Costly (answer)

(i) This dress is Costly than that.

Answer 2

This dress is more costly than that.

• (d) more costly is the correct option.
• The given question is a sort of verbal proficiency question where there will be a sentence with missing words, and we are expected to complete the sentence with the most applicable word or phrase from the given options.
• The given sentence is a comparative sentence so the comparative degree of adverb needs to be used. The comparative form of costly is more costly or costlier
• However, Both of them are grammatically correct but "more costly" is the widely used one whereas, "Costlier" is used rarely and sounds a little odd to a native ear.
• The comparative degree is the form of an adverb or adjective that is used when there the sentence demands comparing two things.

Hence, This dress is more costly than that.
