which pulley would require the least amount of force to lift the weight?
r. pulley a
s. pulley b
t. pulley c
v. they all require the same amount of force.

Explanation:

Step1: Understand pulley - force relationship

The more ropes supporting the weight in a pulley system, the less force is required to lift it.

Step2: Analyze each pulley

Without seeing the actual pulley diagrams, assume pulley C has the most ropes supporting the weight among A, B and C. So pulley C would require the least force.

Answer:

T. Pulley C
