What is a way that biotechnology can most directly improve agriculture?

a) by increasing the need for genetic engineering of fish
b) by eliminating the need to produce products in the laboratory
c) by improving the nutritional value of fish
d) by reducing the use of farming to produce seafood

A) By increasing the need for genetic engineering of fish    

Fish is a globally accepted source of food, with the increase in population all over the world the demand for fish as a source of food is also increasing. Genetic engineering is a field of biotechnology in which the genome of the organism is manipulated by addition, deletion or substitution. This is done to improve the productivity of the animals and plant crops and to obtain desires characteristics in them.

A) By increasing the need for genetic engineering of fish is the correct option which can directly improve fish agriculture because a fish species can be genetically modified so that it can be able to produce more number of offsprings and nutritious quality of flesh, useful for human consumption.  

i think it is d. objects resist changes in their state of motion.
