Explanation:
Detailed explanation-1: -Hydrosere is the primary succession sequence which develops in aquatic environments such as lakes and ponds. It results in conversion of water body and its community into a land community.
Detailed explanation-2: -So, the correct answer is ‘Submerged plants → Floating plants → Reed swamp stage → Sedges’.
Detailed explanation-3: -The first plant to colonise an area is called the pioneer community. The final stage of succession is called the climax community.
