Question

some objects in space are created from clouds of gas and dust. what will happen if the cloud does not have enough mass? a star will form. a star will not form. a protostar will form. a nebula will not form.

Explanation:

Stars form when gas/dust clouds have enough mass to collapse under gravity, generating the high pressure and temperature needed for nuclear fusion. A cloud with insufficient mass cannot reach these conditions, so a star will not form. A protostar requires enough mass to start gravitational collapse, and the cloud itself is a nebula (so the nebula already exists here).

Answer:

B. A star will not form.
