    E) None of these

    Correct Answer: B

    Solution :

    Explanation: Option (b) is correct. Number of students in the class = 151 Number of books that each student has = 12 Therefore, total number of books = \[151\times 12=151\times (10+2)\] = \[\text{(151}\times \text{10)}+(151\times 2)=1510+302=1812\]
