Some objects in space are created from clouds of gas and dust. What will happen if the cloud does not have enough mass?

A core will form.

A star will not form.

A protostar will form.

A nebula will not form.

Some objects in space are created from clouds of gas and dust. A star forms when the mass of the dust cloud is large and has enough hydrogen to start creating a protostar and sustain the nuclear fusion reaction within the core of the protostar. If the dust cloud is not dense enough, then the star formation does not take place, rather a nebula is formed, example the Horse-head nebula. So the answer is (B) A star will not form.
