2 of 4

Explanation:

To identify Label A, we analyze the cell structure. The nucleus is typically a large, roundish structure in the cell (often with a distinct appearance), and in the diagram, Label A matches the nucleus's typical location and appearance. The Golgi apparatus has a different, more stacked or flattened appearance, and mitochondria are smaller, oval - shaped with internal membranes. So Label A is the nucleus.

Answer:

nucleus
