Correct answer: No — option 4.

Reason: 11^2 = 121 and 12^2 = 144, and 136 lies between them, so no whole number squared equals 136.

(Options 1–3 are incorrect: option 1 gives wrong arithmetic; option 2 falsely claims all perfect squares are even; option 3 wrongly assumes a sum of perfect squares is always a perfect square.)
