Correct answer: 9
Explanation:
A composite number has more than two factors (not a prime number).
Let's check each option:
- 3 → Prime number
- 5 → Prime number
- 7 → Prime number
- 9 → Factors: 1, 3, 9 → more than two factors
So, 9 is the smallest odd composite number.
Directions: In the Question, a statement of Assertion
(A) is followed by a statement of Reason (R).
Choose the correct option from the following:
Assertion (A): For two odd prime numbers \(x\) and \(y\), \((x + y)\), \(\text{LCM}(2x,\ 4y) = 4xy\)
Reason (R):} \(\text{LCM}(x, y)\) is a multiple of \(\text{HCF}(x, y)\)
