      A 2 Correct Answer Incorrect Answer
      B 3 Correct Answer Incorrect Answer
      C 4 Correct Answer Incorrect Answer
      D 5 Correct Answer Incorrect Answer

      Solution

      Number of zeros will depend on how many times 10 i.e. (5 Γ— 2) occur in the product Since, 28 Γ— 45 Γ— 80 Γ— 25
      = 7 Γ— 2 Γ— 2 Γ— 9 Γ— 5 Γ— 8 Γ— 2 Γ— 5 Γ— 5 Γ— 5 Since, (5 Γ— 2) occurred four times in the given product Therefore, required number of zeros = 4
