Expert Answer:

c) Radish and carrot, since they are similar in basic fundamental structure and origin, but dissimilar in function.     d)  Wings of an insect and wings of a bat. Bat wings and insect wings show similar function but are not derived from a common ancestor. Similar conditions and a similar environment caused both species to separately evolve similarly built structures.
