Solution

The correct option is A Rapid rate of renaturation
Renaturation in molecular biology refers to the reconstruction of a protein or nucleic acid (such as DNA) to their original form especially after denaturation.
The reassociation kinetics of repetitive DNA is faster than the non-repetitive DNA because the complementary sequence of the repetitive DNA is more in the genome as compared to non-repetitive DNA. So, repetitive DNA easily finds a complementary sequence as compared to non-repetitive DNA.
