Explanation:

- Option 1: "Ashutosh kumar said that BJP has always held immense faith in star charisma."

- Uses "has held," which is present perfect tense. It suggests continuity from the past until now.

- Option 2: "Ashutosh kumar said that BJP had always held immense faith in star charisma."

- Uses "had held," indicating past perfect tense. Implies the faith was held before a specific time in the past.

- Correct choice as it accurately backshifts the tense when reporting speech.

- Option 3: "Ashutosh kumar said that BJP have always held immense faith in star charisma."

- Uses "have held," which is grammatically incorrect because "BJP" is a singular entity, so "has" is needed.

- Option 4: None of these.

- Not applicable since option 2 is correct.
