Correct option is C
Option (c) contains an error.
Error Explanation: The phrase “led to his squad” is incorrect.
The correct phrase should be “led his squad” because the subject (he) is leading his squad, not being led to it.
Correct Sentence: He had led his squad of commandos towards the target of a group of houses when he spotted enemy soldiers hiding in the houses.
Grammatical Rule Used:
→ Causative and active voice structure of past perfect tense.
Example: She had led the team to victory.
Information Booster: “To lead someone to” implies guidance to a place, while “lead someone” implies command over a group.
