Answer 2

Answer:

Squares of odd numbers are odd numbers only. That means they can't be divided by 2. Hence, the answer is 361

Step-by-step explanation:

From the above-given options, we have:

256 = 16 * 16 _________________(i)

361 = 19 * 19  _________________(ii)

144 = 12 * 12 _______________(iii)

400 = 20 * 20 ______________(iv)

From, (i),(ii), (iii), &(iv), we obtain that only 19 is odd number.

Therefore, 361 is the square of an odd number.
