Which of the following sentences contain a linking verb?

Sammy made lunch for us yesterday. +++
Would this be correct?

This should help you. Keep in mind that a linking verb simply links a noun to a phrase or word that describes it. It involves no action, as in Sammy making lunch or someone driving to a destination or chopping down a tree, etc.

C. The turkey sandwiches looked delicious.

the turkey sandwiches (<subject) LOOKED (<linking verb) delicious.

I don't see the other options.

"made" is not a linking verb. Sammy did something, so it is an active verb.

A. Sammy made lunch for us yesterday. (my answer)

B. I smelled the delicious fruit salad.
C. The turkey sandwiches looked delicious.
D. We want lunches from Sammy every day now! @Reed
