Answer:

I would say that the correct answer would probably be The genes of a crop are manipulated to be insect resistant.

Explanation:

Crop gene manipulation produces GMOs, which are a form of Biotech.

Biofuel development is the other one it might (probably won't) be, as Biofuel is an example of biotech too. However, I don't think making the purifying process more efficient is considered an example of biotech.

Good luck! :)
