Explanation / Answer

A single clone of interest can be distinguished from others in a mixture of clones by:
A. Testing the clones for antibiotic resistance

This is because the single clone of interest would have not only acquired the gene of interest but would also be expressing an antibiotic resistance gene in association with it thus conferring upon it the resistance. Resistance to damage by ultraviolet light is not the right answer, and as much as a specific probe, usually labeled complementary DNA sounds like a good option, it would only be true for exposed genetic material and not these clones that are carrying it inside themselves.
