Detailed explanation-1: -Secondary succession can be described as the colonization of a habitat that once supported plant and animal life but was abandoned due to ecological disturbance. Types of ecological disturbances such as hurricanes and floods can empty a habitat.

Detailed explanation-2: -So the correct option is ‘it occurs on a deforested site’.

Detailed explanation-3: -Secondary succession is the ecological succession that occurs after the initial succession has been disrupted and some plants and animals still exist. It is usually faster than primary succession as soil is already present, and seeds, roots, and the underground vegetative organs of plants may still survive in the soil.
