a slimy mass of multinucleate protoplasm, having pseudopodia-like structures for engulfing food, reproduction through fragmentation or spores.

(B) Step $1$: Myxomycetes are commonly known as acellular slime molds.Step $2$: They consist of a slimy mass of multinucleate protoplasm called a $plasmodium$.Step $3$: They exhibit amoeboid movement using pseudopodia to engulf food particles.Step $4$: Their reproduction occurs through the formation of spores or by fragmentation of the $plasmodium$.Therefore, option $(B)$ is correct.
