The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept
Biodiversity is studied at three linked levels.

Step 2: The levels
Genetic diversity is the variation of genes within a species, i.e. intraspecific diversity. Species diversity is the variety of species in a region, i.e. interspecific diversity. Ecological diversity is the variety of habitats, communities and ecosystems.

Step 3: Conclusion
So the three levels are intraspecific, interspecific and ecological diversity.

Final Answer:
The three levels are interspecific, intraspecific and ecological diversity. \[ \boxed{\text{(C) }\text{interspecific, intraspecific and ecological}} \]
