Solution
The correct option is C Single-stranded DNA molecule
A probe can be defined as a labeled sequence of DNA or RNA that is used to identify the specific sequence of nucleotides in the DNA strand. These probes can be synthesized in the laboratory, with a sequence complementary to the target DNA sequence. They are radiolabeled so that their presence in the target DNA can be traced easily. These probes are single-stranded to allow their base-pairing with the target DNA strand. Hence, the correct answer is the option C.
