The correct answer is **4**.

Hemoglobin is a complex protein found in red blood cells that is responsible for transporting oxygen from the lungs to the tissues and returning carbon dioxide from the tissues back to the lungs. Each hemoglobin molecule consists of four subunits, each containing a heme group, which has an iron atom at its center. This iron atom can bind to one molecule of oxygen (O₂). Therefore, since there are four heme groups in a hemoglobin molecule, each hemoglobin can carry up to four oxygen molecules simultaneously.

Thus, the binding process goes as follows:

1. Each of the four heme groups can each bind one molecule of O₂.
2. When fully saturated, a single hemoglobin molecule can therefore transport 4 O₂ molecules.

This highly efficient mechanism allows the blood to deliver adequate oxygen levels to tissues throughout the body, which is essential for cellular respiration and sustenance of life.
