If the HCF of p and q (p > q) is G, then which of the following statements is/are correct ? I. HCF of p and (p + q) is G II. HCF of p, (p - q) is G Select the answer using the code given below :

  1. A. I only
  2. B. II only
  3. C. Both I and II
  4. D. Neither I nor II

Correct Answer: C. Both I and II

Explanation

By the properties of the Euclidean algorithm, if G is the HCF of p and q, it must also be the HCF of p and p+q, as well as the HCF of p and p-q. Therefore, both statements are correct.
