Select the option that will improve the highlighted part of the given sentence.
She is educated than her sister.

Correct option is B

The correct substitution of the highlighted words is (b) more educated.
Explanation:
When comparing two entities using adjectives with more than one syllable (like 'educated'), we use "more" + adjective instead of "-er" form.
Grammatical Rule Used: For adjectives with more than two syllables, "more" is used in comparative form.
Example:
Incorrect – She is educated than him.
Correct – She is more educated than him.
Information Booster:
"More" is used before adjectives ending in -ed, -ful, -ous etc., like: more successful, more beautiful, more careful.
