Identify the part of speech or the form of a part of speech in the underlined portion of each sentence.

The yellow house down the street from me is for sale.
a. preposition
b. conjunction
c. adjective
d. adverb

I think it's A, since down is followed by a noun, but want to be sure. Seems like it could also be C. since it's describing?
Thanks
