Answer:

B. Presence of a nucleus in Paramecium.

Explanation:

Streptococcus are bacteria, which are classified in kingdom Monera. These are unicellular, prokaryotic organisms, in which true nucleus is not present as they lack membrane-bound organelles.

Paramecium is a protist, which belongs to kingdom Protista. They are unicellular, eukaryotic organisms, in which membrane-bound organelles, such as nucleus, endoplasmic reticulum and mitochondria are present.

Thus, the correct answer is option B.
