• A. Infertile
• B. Not infertile
• C. Not growing together in a common habitat
• D. Growing together in a common habitat

Answer 1

Answer: (C)

Not growing together in a common habitat

Reproductive isolation refers to a barrier that prevents animals of the same group from breeding. Mainly three different types of reproductive isolation are seen.

1. Temporal isolation: two species will never come to contact since they have different mating seasons.
2. Behavioral isolation: where one species does not know the mating rituals of the other
3. Mechanical isolation: where the organism will try to mate but are physically unable.
4. Ecological isolation: where two species have different habitats and are not growing together.

So the correct option is C
