Directions: The sentence given below has three underlined parts named A, B and C. Choose the part of the sentence that contains an error as your answer. If there is no error, mark (D).

(A) If he will work (B) hard, (C) he will get promotion. (D) No error

The error is in part (A). In conditional sentences (Type 1), the if-clause should use simple present tense, not 'will'. The correct structure is 'If he works hard, he will get promotion'. Using 'will' in both the if-clause and main clause is redundant and grammatically incorrect. The simple present 'works' is required in the if-clause.
