Best answer
The correct choice is (c) Struggle for existence

Explanation: Struggle for existence was a concept of Darwin and not Lamarck’s. It states that every species competes with the same and other species for food, shelter, etc. to survive. Whereas, the remaining options support Lamarck’s concept of inheritance of acquired characters.
