The superlative form of an adjective should only be used when comparing B. more than two things.
We use a superlative adjective to describe one thing in a group of three or more things:
- Mount Everest is the highest mountain in the world.
- My mother's cooking is the best in the family.
- You have the curliest hair I have ever seen.
We use the superlative form of an adjective when comparing B) MORE THAN TWO THINGS.
Superlative adjectives express the extreme or highest degree of a quality of one thing in a group of things.
The other options are incorrect because when we compare two things we should use comparative adjectives and if we are just describing a person we use adjectives in their base form.
