A
universe
B
galaxy
C
nebula
D
planets
Explanation: 

Detailed explanation-1: -The birthplace of a star is nebula which is made up of dust particles and gases. These are present in the interstellar space, i.e., the space between the stars.

Detailed explanation-2: -Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.

Detailed explanation-3: -Where are nebula located? Nebula are often found in the space between stars, known as the interstellar medium. On average, this region contains only around one atom per cubic centimetre. However, in certain places the density can be significantly higher than this ⁠-high enough to become visible through a telescope.

Detailed explanation-4: -A STAR IS BORN – STAGES COMMON TO ALL STARS All stars start as a nebula. A nebula is a large cloud of gas and dust. Gravity can pull some of the gas and dust in a nebula together. The contracting cloud is then called a protostar.
