The mass in the figure can slide on a frictionless surface. When the mass is pulled out, spring 1 is stretched a distance `x_(1)`and spring 2 is stretched a distance `x_(2).` The spring constants are `k_(1) and k_(2)` respectively. Magnitude of spring force pulling back on the mass is

A

`k_(1)x_(1)`

B

`k_(2)x_(2)`

C

`(k_(1)x_(1)+k_(2)x_(2))`

D

`0.5(k_(1)+k_(2))(x_(1)+x_(2))`
