Correct option is A
Option (a) contains an error.
Explanation: The segment “will be exercised” is in passive voice, which is incorrect in this context.
The correct phrase should be “will exercise” as “the stars” is the subject performing the action of exercising influence.
Correct sentence: “Hardik’s horoscope says that the stars will exercise a benign influence on his life.”
Grammatical rule used:
- Use active voice when the subject is performing the action.
- Structure for simple future active: Subject + will + V1 + object
Example: The teacher will explain the chapter tomorrow.
