Solution

The correct option is B $T_{s}$ remains same, $T_{p}$ decreases

Time period of a spring and time period of a pendulum in an upward accelerating lift are given by
$T_{s} = 2 π \sqrt{\frac{m}{k}}$
$T_{p} = 2 π \sqrt{\frac{l}{g_{e f f}}} = 2 π \sqrt{\frac{l}{g + a}}$
We can see that $T_{s}$ is independent of the acceleration of the lift, while $T_{p}$ is inversely proportional to the acceleration. due to which $T_{s}$ remains the same, while $T_{p}$ decreases.
