Quizplus · Accepted Answer

The figure shows CH₄ (methane) as part of the carbon cycle, which is one of the options in choice C. Additionally, HCO₃- (bicarbonate) and CaCO₃ (calcite) are also shown as part of the cycle, which are the other two options in choice C. The other choices do not include these three chemicals as part of the carbon cycle.
