    Statement-1: When two semiconductor of p and n type are brought in contact, they form p-n junction which act like a rectifier.
    Statement-2: A rectifier is used to convert alternating current into direct current.

    A)  Statement-1 is false, Statement - 2 is true.

    B)  Statement-1 is false, Statement - 2 is true. Statement-2 is a correct explanation for Statement-1.

    C)  Statement-1 is true, Statement -2 is true; Statement -2 is not a correct explanation for Statement -1

    D)  Statement-1 is true, Statement-2 is false

    Correct Answer: C
