Though like waves breaking it may be, or like a changed familiar tree, or like a stairway to the seawhere down the blind are driven. which kind of figurative language is used in lines 45-48 of the poem?

simile

Explanation:

A simile is a comparison between two different things using like or as. There are three similes in these lines. The comparisons are between "it" and "waves breaking", "a changed familiar tree", and "a stairway to the sea". These are all similes because they use "like" to make the comparison. Metaphors are also comparisons between two different things but they do not use like or as.
