In case you can.

In case you can.

It's regulating service only. Genetic diversity allows a species to adapt itself effectively to the environment around and in turn keeps the ecosystem rich.


Don't assume answer before looking at the options given. If you look at the 4 points given, you will find a pattern, it's only medicines that stand out. Rest of the three in some or the other way helps in maintenance of ecosystem. But we are not directly getting any product or service in hands by genetic diversity. Biodiversity is a different thing again.

Not with this particular question but there might be some questions in the actual exam where you feel no option is totally correct. Even in the instructions written on question paper they say choose the closest possible answer.
So mock practice should get you to such kind of thinking where you will be able to find a pattern and arrive at most possibly correct answer.

Good luck!
