Manger's computer: Mangere's computer of a cell is DNA because it stores the information of cell-like computer memory.

Incinerator power unit: Mitochondria transforms glucose (sugar) into an energy molecule known as ATP.
Head office: Nucleus has control over the entire cell. The DNA, which is present in the nucleus, codes for the proteins, which is necessary for the cell to work and grow. Since it has control over the entire cell, it will be the correct answer.
