Explanation:
Let's look at each organelle's role in the cell.
A. Mitochondria
Often called the "powerhouse of the cell" because it produces ATP, or energy through cellular respiration. It holds some DNA, but not the majority.
B. Nucelus
The control center of cell and houses the majority of the genetic information (DNA)
C. Chloroplast
Produces glucose for plant, algae, and some bacteria cells through photosynthesis.
D. Golgi body
Transports and packages substances, like proteins and lipids.
The nucleus contains most of the genetic material in a cell.
