Consider the following statements in respect of prime numbers p and q:
Which of the statements given above is/are correct?
Neither I nor II
Since prime numbers are either 1 or themselves, their LCM is always an odd number (if they are both odd) and their HCF is 1, making the sum odd. Hence, neither statement I nor II is entirely correct. Therefore, the correct answer is (d) Neither I nor II.
