All Options:

  • D49\displaystyle 49

Detailed Solution & Explanation

Let's analyze the properties of the numbers 15,25,37,49\displaystyle 15, 25, 37, 49:
- 15\displaystyle 15 is a composite number (15=3×5\displaystyle 15 = 3 \times 5).
- 25\displaystyle 25 is a composite number (25=5×5\displaystyle 25 = 5 \times 5). It is also a perfect square.
- 49\displaystyle 49 is a composite number (49=7×7\displaystyle 49 = 7 \times 7). It is also a perfect square.
- 37\displaystyle 37 is a prime number.

Since 37\displaystyle 37 is the only prime number in the given set (while the others are all composite), it is the odd man out.

Hence, **Option C** is the correct answer.
