Correct option is A
The correct substitution of the highlighted words is (a)
bigger.
Explanation: The sentence requires a
comparative degree because a comparison is made between “he” and “his friends”.
Grammatical Rule Used:
Comparative adjectives (e.g., taller, smarter,
bigger) are used when comparing two nouns and are followed by
“than” (not “then”).
Example: She is
taller than her brother.
Information Booster:
"Then" refers to time; "than" is used for comparisons.
Incorrect options:
· (b)
more big – incorrect form (use “bigger” instead)
· (c)
biggest – superlative form, used when comparing more than two
· (d)
most big – incorrect form
