The correct option is C style of
Let’s examine sentence with blank no. 41: “If the students practice writing for the school magazine, their ____(41)___ writing will be much improved.” Blank no. 41 requires phrase related to the action of writing. A phrase is a group of words that stand together as a single unit, typically as part of a clause or a sentence. A phrase does not contain a subject and verb and, consequently, cannot convey a complete thought. Options A and B cannot be used as they are not used for the action of writing. Option D cannot be used as it is not a phrase because it contains the verb, ‘use.’ Hence, Option C is the correct answer.
