Please answer my question

Dear Student,

It is clear from the image that the load is  T+T+T+T =4T  =4 N(If T= 1 N)

As we know that in a system of 4 pulleys if the load moves up through a distance of d, then each segment of the string is loosened by a length d so the effort end moves through a distance of 4 times of d.
Velocity ratio =4ddTherefore, velocity ratio is 4
So, option (f) is correct
