Question

which sentence uses this meaning of bluff?
bluff noun a steep cliff
the view from the top of the bluff was incredible.
if you bluff during the game, mr. harding is sure to see right through it.

Explanation:

We need to find the sentence where "bluff" means "a steep cliff". In the first sentence, "the top of the bluff" refers to the top of a steep cliff, so the view from there makes sense. In the second sentence, "bluff" is used as a verb (to deceive or pretend), which doesn't match the noun meaning of a steep cliff.

Answer:

The view from the top of the bluff was incredible.
