Solution

The correct option is D
0

Step 1: Given data:
if the rope of lifts breaks suddenly.
Diagram:

Step 2: Formula used:
When the motion of the lift is in downward direction the tension equation is
$T = m (g - a)$
Step 3: Calculating the tension:
If the rope of the lift breaks suddenly, acceleration becomes equal to g
so that tension,
$T = m (g - g) = 0$
Hence, option D is the correct option.
