Question

which of the following would require the use of recombinant dna

Answer 1

What are the choices

Answer 2

crossing two apple trees to create better apples
breeding a donkey and a horse to make a mule
engineering bacteria that produce human insulin
creating a polyploid banana tree

Answer 3

C

Answer 4

Engineering bacteria to produce insulin is a use of recombinant DNA (SaveahThomas's answer), I think is correct. Crossing two apples to make better ones requires no DNA manipulation, just pollenation. Breeding a horse and a donkey does not alter the DNA sequence of either animal, and most plants are naturally polyploid.
