The force that the construction crew must apply to the lever can be found by using the formula for mechanical advantage, which is:

Mechanical Advantage = Output force / Input force

Given that the mechanical advantage is 6 and the lever applies a force of 1600 N to the rock, we can rearrange the formula to solve for the input force:

6 = 1600 N / Input force

Input force = 1600 N / 6 = 267 N

Therefore, the force that the construction crew must apply to the lever is 267 N.

So the correct answer is 267 N.
