      A 4 Correct Answer Incorrect Answer
      B 3 Correct Answer Incorrect Answer
      C 5 Correct Answer Incorrect Answer
      D 6 Correct Answer Incorrect Answer

      Solution

      P3 + 3P2 + 3P = 7
      P3 + 3P2 + 3P + 1= 8
      (P + 1)3 = (2) 3
      P + 1 = 2
      P = 1
      So, P2 + 2P = (1)2 + 2 × 1
      = 1 + 2 = 3
