Options

A. power house
B. energy transducer
C. disposal units of cell
D. all correct

Answer

### Step-by-Step Solution:

1. **Understanding Lysosomes**: Lysosomes are membrane-bound organelles found in the cytoplasm of eukaryotic cells. They contain digestive enzymes that help break down waste materials and cellular debris.
