The reactions of cellular respiration occur in the mitochondria and cytoplasm of the cells of eukaryotes. So, the answer is Both B and C.

Here's a step-by-step explanation:

1. Glycolysis, the first step of cellular respiration, occurs in the cytoplasm. During glycolysis, one molecule of glucose (a six-carbon sugar) is broken down into two molecules of pyruvate (a three-carbon compound).

2. The next step, the citric acid cycle (also known as the Krebs cycle), occurs in the mitochondria. Here, each pyruvate molecule is further broken down and stripped of electrons, which are transferred to carrier molecules. This process also produces a small amount of ATP.

3. The final step, oxidative phosphorylation, also occurs in the mitochondria. The electrons carried by the carrier molecules from the previous step are used to create a flow of protons across the mitochondrial membrane. This flow drives the synthesis of ATP, the main energy currency of cells.

So, while the nucleus and chloroplasts have important roles in the cell, they are not the main sites of cellular respiration in eukaryotes.
