D) protein.
Adenosine Triphosphate
A high-energy molecule found in the cells of all living things, serving as a primary energy carrier.
Energy
The capacity to do work, which in biological systems is derived from the chemical energy stored in foods or from sunlight in photosynthetic organisms.
Muscles

Final Answer :
B
Explanation :
Adenosine triphosphate (ATP) is the primary source of energy used by our muscles for contraction. When ATP is broken down, energy is released to power muscle movement. Oxygen is necessary for the production of ATP through cellular respiration, but it is not directly used as fuel by our muscles. Lactic acid is a byproduct of anaerobic metabolism when there is insufficient oxygen available to produce ATP, and protein is not a primary source of energy for our muscles.
