The picture shows mutual relationship between the fig tree and the wasp.
I:
Many species of fig trees can only be pollinated by their ‘partner’ wasp species and no other species.
II:
The female wasp does not derive any benefit from this relationship.
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
