(B) To determine the nature of the number,we simplify the expression: $3 \times 15 \times 11 + 11$ $= 11 \times (3 \times 15 + 1)$ $= 11 \times (45 + 1)$ $= 11 \times 46$ $= 11 \times 2 \times 23$ Since the number can be expressed as a product of prime factors other than $1$ and itself (i.e.,$2, 11, 23$),it is a composite number.
