Option 1 : A

The correct answer is- 'error lies in the part-A'

  • Using 'predicted' in place of 'predict' to make the sentence correct.
  • We know that 'have, has, had' are the helping verbs of perfect tense and they always take the third form of the verb(V3).
  • Structure of Present Perfect: Sub + has/have + V3 + object
    • Example: Ram has gone to market.

The correct sentence is- Experts have predicted that within ten years ethanol will emerge as the primary automatic fuel in the world.
