Explanation / Answer

Answer Option D.

The first three options can be studied by scientists over a long time period. Here, tagging involves capturing the organism, tagging them and injecting them with a chemical/ medicine and then following them over a period of time using different tracking devices. These studies are very useful in population biology, reproductive biology, pollution studies etc.
