The breakdown of pyruvate to give carbon dioxide, water, and energy takes place in:

(b) mitochondria.

Explanation: Mitochondria are like tiny power plants inside our cells. They take pyruvate, which is a molecule made from glucose, and break it down to produce energy, carbon dioxide, and water. This process is called cellular respiration and it helps our cells get the energy they need to function.
