Question

Fill in the blank with the most appropriate option.
This is the ________ suit I have ever bought.

• A. more expensive
• B. most expensively
• C. most expensive
• D. more expensively

Answer 1

The correct option is C most expensive

The Superlative Degree denotes the existence of the highest degree of the quality. It is used when more than two things are compared.
The given sentence is in superlative form and adjective used should be in superlative form too. Hence, Option C: 'most expensive' is the correct answer.
'Expensively' is an adverb and not an adjective, so Option B and Option D are incorrect.
Option A: 'more expensive' is in comparative form so it is incorrect.
