A nebula is:
A
A cloud of ice
B
A cloud of dust and gas
C
A cloud of just gas
D
A cloud of just dust
Explanation: 

Detailed explanation-1: -A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called “star nurseries."

Detailed explanation-2: -Dark nebulae – or absorption nebulae – are clouds of gas and dust in space that are dense enough to obscure and block light from background stars. These vast clouds are mostly composed of molecular hydrogen. They’re often locations where material is coalescing to form new stars.

Detailed explanation-3: -A planetary nebula is a region of cosmic gas and dust formed from the cast-off outer layers of a dying star. Despite their name, planetary nebulae have nothing to do with planets.

Detailed explanation-4: -Planetary nebulae are the shells of gas and dust ejected from dying stars. Webb’s powerful infrared view brings this nebula’s second star into full view, along with exceptional structures created as the stars shape the gas and dust around them.

Detailed explanation-5: -A Nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases from red giant stars late in their lives.
