What is the rhyme scheme in this excerpt from Longfellow's, "The Tide Rises, the Tide Falls?"

The tide rises, the tide falls,

The twilight darkens, the curlew calls;

Along the sea-sands damp and brown

The traveler hastens toward the town,

And the tide rises, the tide falls.

A) aabba

b) ababa

c) abaca

d) abcca

The rhyme scheme in this excerpt from Longfellow's "The Tide Rises, the Tide Falls" is A. aabba.

A stands for the words falls, calls, and in the end, falls again. B stands for brown and town, which rhyme as well. There is no C in the rhyme, because there are only two sounds that rhyme, the first, second, and last line sound the same, and the third and fourth line also sound the same.
