Answer:
Option B is correct

Step-by-step explanation:
Given the equation:-

Divide both sides by 2 we have;

Taking square root both sides we have;
![\sqrt[2]{x^2} =\pm \sqrt{121}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7Bx%5E2%7D%20%3D%5Cpm%20%5Csqrt%7B121%7D)
We can write 121 as:

then;
![\sqrt[2]{x^2} =\pm \sqrt{(11)^2}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7Bx%5E2%7D%20%3D%5Cpm%20%5Csqrt%7B%2811%29%5E2%7D)
Simplify:

Therefore, the solution for the given equations is,
