Assertion: Parasitoidism is a strategy that is actually closer to predation.
Reason: A parasitoid is an organism that lives in close association with its host and at the host's expense, and which sooner or later kills it.

2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false

Assertion: Differences among similar species whose distributions overlap geographically are accentuated in regions where the species co-occur.
Reason: The differences are minimized or lost where the species’ distributions do not overlap.
