Option B, Nucleoid region
The DNA of a bacterial cell is found in its nucleoid region, not in a nucleus, capsule, or ribosomes. The nucleoid is an area in the bacterial cell where the genetic material is located.
The DNA of bacterial cells is found in its nucleoid region. Bacteria do not have a nucleus, a characteristic feature of eukaryotic cells, and their genetic material is instead located in a region of the cell called the nucleoid. The nucleoid is not bound by a membrane, unlike the nucleus in a eukaryotic cell. Therefore, options a (capsule), c (nucleus), and d (ribosomes) are not correct. There are various other parts of a bacterial cell. For example, the capsule provides protection to the bacterial cell, while ribosomes are responsible for protein synthesis.

Gas exchange in the respiratory system occurs in the alveoli, which are small air sacs located in the lungs. Oxygen diffuses from the alveoli to the capillaries, while carbon dioxide diffuses from the capillaries to the alveoli.
Gas exchange in the respiratory system takes place in the alveoli, which are small air sacs located at the ends of the respiratory bronchioles. These structures are found within the lungs. The alveoli are surrounded by capillaries, which are tiny blood vessels.
When we breathe in, oxygen from the air enters the alveoli and diffuses across the thin walls of the alveoli and capillaries. At the same time, carbon dioxide, a waste product, diffuses from the capillaries into the alveoli to be removed when we exhale.
So, the gas exchange occurs between the alveoli and the capillaries surrounding them.
