Select the option that will improve the highlighted part of the given sentence.
Rhea and Heena are both great dancers, but Rhea is the best.

Correct option is B

The correct substitution of the highlighted words is (b) but Rhea is better.
Explanation:
· The original sentence compares two people: Rhea and Heena.
· When comparing two entities, we use the comparative degree of adjectives, not the superlative.
Grammatical Rule Used:
· Use the comparative form (better, taller, smarter) when comparing two people or things.
· The superlative form (best, tallest, smartest) is used when comparing more than two.
Corrected Sentence:
Rhea and Heena are both great dancers, but Rhea is better.
Example:
· Incorrect: Between John and Alex, John is the tallest.
· Correct: Between John and Alex, John is taller.
Information Booster:
· Common Comparatives:
· good → better → best
· tall → taller → tallest
· bad → worse → worst
Why Other Options Are Incorrect:
· (a) one of the best – implies a larger group, not just two people
· (c) both of are – grammatically incorrect (“both of them are” is needed)
· (d) is good – lacks contrast; doesn’t show comparison
