If sinus arrest occurs, usually another area of the heart takes over pacemaker activity. This area is called an escape pacemaker.

Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption
Option A is correct
