Correct option is B
Solution:
To identify if a number is a perfect square, we take the square root of each number and check if the result is an integer.
1. A) 222
√222 ≈ 14.899, which is not an integer, so 222 is not a perfect square.
2. B) 196
√196 = 14, which is an integer, so 196 is a perfect square.
3. C) 124
√124 ≈ 11.14, which is not an integer, so 124 is not a perfect square.
4. D) 141
√141 ≈ 11.87, which is not an integer, so 141 is not a perfect square.
Thus, the only perfect square is 196.
