After the concert, his voice has hoarse from cheering.

Correct option is B

The correct substitution of the highlighted words is (b) voice was.
Explanation:
The sentence "After the concert, his voice has hoarse from cheering." contains a grammatical error due to incorrect verb usage and tense.
· The phrase "has hoarse" is incorrect because "hoarse" is an adjective, and adjectives cannot be used directly with "has" (a helping verb requiring a past participle for perfect tense).
· The correct construction should be: “his voice was hoarse”, where “was” is the simple past form of the verb to be, which links the subject with the adjective hoarse.
Grammatical Rule Used:
Linking Verb + Adjective
Adjectives follow linking verbs like is, are, was, were, become, seem to describe the subject.
· ❌ Incorrect: has hoarse
· ✅ Correct: was hoarse
Example:
· Incorrect: She has angry after the meeting.
· Correct: She was angry after the meeting.
Information Booster:
In perfect tense, we use "has/have/had" + past participle (V3). But "hoarse" is not a verb — it’s an adjective, so it cannot be used with "has".
