Select the correctly punctuated sentence.

A) It was an exhausting complicated surgery.
B) It was an exhausting, complicated surgery.
C) It was an exhausting, complicated surgery

My answer is B

Right.

Thanks:)

Correct! The option B) "It was an exhausting, complicated surgery." is the correctly punctuated sentence. In this sentence, a comma is used to separate the adjectives "exhausting" and "complicated" to make the meaning clear. The comma serves to indicate that both adjectives are describing the noun "surgery" and should be read together as a unit. The absence of a comma in option A) and option C) makes them incorrect. Well done!
