The stomach select one:

a. secretes lipases that complete fat digestion.

b. serves as a temporary storage site

c. manufactures bile.

d. contents are highly alkaline.

I would say it's b.

stomach doesn't secrete lipase, only pancreas does.

stomach also doesn't manufactures bile, the liver does.

stomach contents are highly acidic, it's around pH 2.0, which is completely opposite to alkaline
