Answer:

Option D

Moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move.

Explanation:

As the name suggests, fixed pulleys are attached to a fixed position and they can't move at all while moving pulleys as their name suggest they are attached to an object and freely move with the object. For a fixed pulley, both parts of a rope are attached to a fixed object like a beam while for a movable pulley, only one part of the rope is attached to a fixed object .
