Answer:
A. Manipulating potato genes to improve nutritional value, growth, and flavor is an example of genetic engineering.
Step-by-step explanation:
Genetic engineering is the process of manipulating an organism's DNA or genetic material to create new traits or characteristics that do not occur naturally. This can be done by adding, deleting, or modifying genes or other genetic elements.
In the example given, scientists are manipulating the genes of potato plants to improve their nutritional value, growth, and flavor. This involves identifying and modifying specific genes that are responsible for these traits, such as genes that control starch production or flavor compounds.
