Final answer:
The mechanical advantage (MA) of the ramp is 3.
Step-by-step explanation:
The mechanical advantage (MA) of a ramp can be calculated by dividing the length of the ramp by its height. In this case, the length of the ramp is 6 m and the height is 2 m. So, the MA would be 6/2 = 3. Therefore, the correct option is C) 3.
