- Carbon has an exceptional ability to bind with a wide variety of other elements.
- C<u>arbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen.</u>

Answer:
Option-B
Explanation:
Dysentery is an abnormal condition that is caused by the infection of the intestine in humans. The infection could be caused by the bacteria or the amoeba.
The disease can be characterized by the cramps in the stomach, diarrhea, and the loss of blood through feces.
Untreated dysentery can lead to the loss of a large amount of blood through feces and will lower the amount of blood in humans.
This severe loss of blood will give rise to another disease called hypovolemic shock is which the heart fails to pump enough blood to the organs due to which the other organs of the body can fail to work properly. This condition can lead to death.
Thus, Option-B is correct.
