b) Hubble Nebula
c) Star Cluster
d) Emission Nebula

Answer 1

An emission nebula is a cloud that glows due to the presence of hot young stars forming within it.

Step-by-step explanation:

A cloud that has hot young stars forming within it and can glow is called an Emission Nebula. These nebulae are made up of interstellar gas and dust, and the light we see is produced when starlight interacts with this gas and dust. The energy from the young stars causes the gas to emit light, resulting in the glowing appearance of the nebula.
