d. it can increase the genetic diversity of a species.

a. It can help detect if a person is prone to certain diseases.

Explanation:

With the help of DNA technology we can get to know the genetic make up of an individual. By doing this, we can easily diagnose whether the individual is prone to certain diseases or not. If we already know the person's susceptibility towards certain diseases then he/she can be directed to avoid practices which may lead him to diseased state. As such we always have options to cure a person using DNA technology itself if he/she has acquired any disease but prevention is always better than cure.
