B Correct answer
Explanation

Planaria is famous for its remarkable regenerative abilities. If a planarian is cut into several pieces, each piece can regenerate into a complete organism. This is due to the presence of specialized stem cells called neoblasts that can differentiate into any cell type needed. Amoeba, Paramecium, and Euglena reproduce primarily by fission but do not have significant regenerative capabilities.
