Change the following from the comparative to the superlative degree of comparison, without changing the meaning of the sentence:

Comparative Degree: An adjective is said to be in the comparative degree when it is used to compare two nouns/pronouns.

When two items/people are compared, a comparative degree is used by putting ‘more’.

Example: She is more cheerful than her sister.

Superlative Degree: An adjective is in superlative degree when it is used to compare more than two nouns/pronouns. We use the article 'the' before the superlative degrees.

When more than two nouns/pronouns are compared, a superlative degree is used by putting ‘most’.

Example: She is the most cheerful girl in the family.

The given sentence is comparative as more has been used for comparison. To convert it into superlative, most should be used and ‘the’ needs to be added before most as this sentence is in superlative degree.

Option A is the correct answer as we have used ‘most’ with article ‘the’ to change the given sentence in superlative degree without changing its meaning.
