An organism was found. It is unicellular, but its one cell does contain a nucleus and the cell is autotrophic. What type of organism is this? A
animalia
B
protista
C
bacteria
D
fungi

B protista

Explanation:

The cell is unicellular, so it can not be an animal, which are all multicellular.

It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)

The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs

Therefore, the organism must be a protist, so the answer is B, protista.

for the points
