B Correct answer
Explanation

For two numbers, Product = HCF × LCM. Here, product = 99 × 2772. Option B (396, 693): HCF of 396 and 693 is 99, and LCM is 2772. Verifying: 396 = 99 × 4, 693 = 99 × 7 (4 and 7 are coprime), and LCM = 99 × 4 × 7 = 2772. Option A has LCM = 1386 (incorrect), Option C has HCF = 33 (incorrect), and Option D has HCF = 1 (incorrect).
