Which action would be most likely scientific research on genetic modification of food?

The most likely action that would constitute scientific research on genetic modification of food is:

Conducting experiments in a laboratory setting to insert or alter specific genes in food crops or microorganisms to improve desirable traits such as pest resistance, nutritional value, or drought tolerance.

This involves controlled experimentation, data collection and analysis, and the application of scientific principles to understand and modify the genetic makeup of food organisms.
