** Option:**

**A.**if both the bracketed terms are right:

**B.**if the first bracketed term is right and second is wrong:

**C.**if the first bracketed term is wrong and second is right:

**D.**if both the bracketed terms are wrong.

**Answer: B . if the first bracketed term is right and second is wrong:**
