Detailed Answer
(d) Growing crops generally are part of the land and
therefore considered real property. However, the crops can be
sold separately from the land, in which case they are considered
personal property under the UCC, whether the buyer or the
seller will sever the growing crops later from the land. Answer
(a) is incorrect because air rights are not discussed in the UCC as
one of those that can be either. Answer (b) is incorrect because
mineral rights are associated with land or realty. Answer (c) is
incorrect because unlike growing crops that may be realty until
sold in a contract, harvested crops are personal property separate
from the realty.
