The correct order of stages in primary succession of a volcanic island is

Volcanic rock-lichen-mosses-sea grasses

Explanation:

Lichens are complex living beings that form a symbiosis of an organism formed by a fungus and an algae or cyanobacterium. They're known for interacting with volcanic rocks. Moss is a cosmopolitan phylum of small, simple-organized, and non-vascular cryptogamous plants that typically grow in dense tufts, which are more common in humid and dark habitats. They're the ones to come after the lichens during primary succession of volcanic island environments. Marine angiosperms, also known as, sea grasses, are the flower-producing plants adapted to life in seawater that form marine meadows on the euphotic bottoms of the oceans. They install themselves on the coasts that are populated by mosses, therefore not being uncommon to see in volcanic islands.
