D

Step-by-step solution

2 steps

The question asks to identify the number that is different from the other three. We need to find a common property among three numbers that the fourth one does not share.

  1. Analyze the divisibility of each number by 4.

    A number is divisible by 4 if its last two digits are divisible by 4.

    • For (A) 3196: The last two digits are 96. Since 96÷4=2496 \div 4 = 24, 3196 is divisible by 4.
    • For (B) 2248: The last two digits are 48. Since 48÷4=1248 \div 4 = 12, 2248 is divisible by 4.
    • For (C) 3036: The last two digits are 36. Since 36÷4=936 \div 4 = 9, 3036 is divisible by 4.
    • For (D) 1258: The last two digits are 58. Since 58 is not divisible by 4 (58÷4=14.558 \div 4 = 14.5), 1258 is not divisible by 4.
  2. Identify the odd one out.

    Numbers (A), (B), and (C) are all divisible by 4, while number (D) is not. Therefore, 1258 is the odd one out.

    The final answer is D\boxed{\text{D}}.
