Naked cytoplasm, multinucleated and saprophytic are the characteristics of

1.  Monera

2.  Protista

3.  Fungi

4.  Slime

(d) Slime moulds are saprophytic protists, moving along the dead leaves engulfing organic material. These are multinucleated and do not possess cell wall and have naked cytoplasm.
Monerans are prokaryotes, which include all bacteria. These do not contain naked cytoplasm.
