MCQ
Statement A (Assertion) : $11 \times 4 \times 3 \times 2+4$ is a composite number.
Statement R (Reason) : Every composite number can be expressed as product of primes.
  • Both assertion (A) and reason ( $R$ ) are true and reason $(R)$ is the correct explanation of assertion (A).
  • B
    Both assertion $(A)$ and reason $(R)$ are true and reason $(R)$ is not the correct explanation of assertion (A).
  • C
    Assertion (A) is true but reason ( $R$ ) is false.
  • D
    Assertion (A) is false but reason $(R)$ is true.

Answer

Correct option: A.
Both assertion (A) and reason ( $R$ ) are true and reason $(R)$ is the correct explanation of assertion (A).
(a): We have, $11 \times 4 \times 3 \times 2+4$
$=(11 \times 3 \times 2+1) 4=67 \times 4=67 \times 2^2$
The given number can be expressed as product of primes. So, it is a composite number.
$\therefore \quad$ Assertion and Reason both are true and Reason is the correct explanation of Assertion.
