D

Verified step by step guidance1
Understand the concept of primary succession: Primary succession occurs in lifeless areas where there is no soil or initial vegetation. It involves the gradual establishment of a biological community in an area that was previously uninhabited.
Identify the characteristics of the locations given in the options: A newly formed volcanic island is a location where there is no pre-existing soil or life, making it a prime candidate for primary succession.
Consider the other options: An abandoned agricultural field, a mature forest after a wildfire, and a pond that has dried up all have pre-existing soil and possibly some remaining life forms, which are more indicative of secondary succession.
Differentiate between primary and secondary succession: Primary succession starts from bare rock or newly formed land, while secondary succession occurs in areas where a disturbance has happened but soil and some organisms still exist.
Conclude that primary succession is most likely to occur on a newly formed volcanic island, as it represents a new, lifeless environment where life must start from scratch.
