Spring $k_1$ is compressed, and $k_2$ expanded by distance x

Using conservation of energy

the total potential energy of the spring= Kinetic energy of the mass

$\large\frac{1}{2}$$k_2x^2+\large\frac{1}{2}$$k_1x^2=\large\frac{1}{2}$$mv^2$

$v=x \sqrt {\large\frac{k_1+k_2}{m}}$

Hence cis the correct answer.
