A
a nebula
B
the Milky Way
C
the Local Group
D
a black hole
Explanation: 

Detailed explanation-1: -A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group. Earth is in the second largest galaxy of the Local Group-a galaxy called the Milky Way.

Detailed explanation-2: -There are over 30 galaxies that are considered to be in the local group, and they are spread over a diameter of nearly 10 million light years, with the center of them being somewhere between the Milky Way and M31. M31 and the Milky Way are the most massive members of the Local Group, with M33 being the 3rd largest.

Detailed explanation-3: -Within the Local Group there are examples of all three main types of galaxies: spirals, ellipticals, and irregulars. The three spirals (the Milky Way, the Andromeda galaxy, and M33) are the most luminous galaxies of the group. The Magellanic Clouds and other irregular galaxies are also fairly bright.
