Which choice below best shows how the speaker changes his mind after taking the other road?

then took the other, as just as fair,
and having perhaps the better claim,
because it was grassy and wanted wear;
though as for that the passing there
had worn them really about the same,

a.) the author uses the words ",fair" and "worn" to contrast the speaker's hopefulness with the doubt he feels later.
b.) the author uses the words ",other" and "same" to contrast the speaker's doubt with the confidence he feels later.
c.) the author uses the words ",took" and "better" to show the speaker's greed and the pride he feels later.
d.) the author uses the words ",grassy" and "worn" to contrast the speaker's love for nature with his later disgust.

i'll give a brainliest to the first person to comment, if it's true.
