1. Exists in a state of equilibrium as the chemical reaction that occurs in the body is:
Hb(aq)+4O_{2}(aq) \rightleftharpoons Hb(O_{2})_4(aq).


2. Combustion processes are never in equilibrium.


3. The amount of C14 in a living organism remains constant but it does not remain constant in decaying matter. This concept is used in Radiocarbon dating to find the age of fossils.

Therefore, the option number (1) is correct.
