a. first
b. second
c. third
d. fourth
please select the best answer from the choices provided.
a
b
c
d

Explanation:

To determine the lever with resistance between the fulcrum and the effort, we recall the types of levers:

• First - class lever: Fulcrum is between effort and resistance (e.g., seesaw).
• Second - class lever: Resistance is between fulcrum and effort (e.g., wheelbarrow, where the load (resistance) is between the fulcrum (wheel) and the effort (handles)).
• Third - class lever: Effort is between fulcrum and resistance (e.g., tweezers).
• There is no fourth - class lever in the standard lever classification.

So, the second - class lever has resistance between the fulcrum and the effort.

Answer:

B. second
