Hint: Biotechnology involves or uses the biological systems, living organisms, or cells in the development of new useful products. It is an important application in the field of medicine, health as well as agriculture.

Complete answer:
The usage and application of biotechnology in the field of agriculture are known as agricultural biotechnology. It is used to improve the yield, as well as in the production of genetically superior crops, which have better disease resistance and stress tolerance. The crops can be incorporated with the desirable genes which provide resistance to diseases as well as pests. Thus from the given options, the important objective of biotechnology in the field of agriculture is to produce pest-resistant varieties of the plant.
-The nitrogen content cannot be improved by biotechnology. It can be done only by the application of fertilizers rich in nitrogen.
-The decrease in the seed number is not a favorable trait in crops. Biotechnology can be used to increase the seed number.
-Increasing the plant weight can also be an objective since weight gain cannot be carried out through biotechnology.
Thus, the most appropriate answer is A, that is, an important objective of biotechnology in the agriculture section is the production of pest-resistant varieties of the plants.

Note: An example of a genetically engineered plant is the Bt cotton. It is a natural pesticide that is a toxin and has the power to kill many fungi and caterpillars, flies, and beetles. Bt is pest specific.
