Best answer
Correct option is (a) Allogenic succession

To explain I would say: Succession driven by the abiotic components of an ecosystem is known as allogenic succession. In contrast, an autogenic succession is driven by the biotic components of the ecosystem. Allogenic succession happens on a time scale that is proportionate with the disturbance.
