Which is the most suitable C/N ratio for growth and fruiting?

Correct option is A

The optimal carbon to nitrogen (C/N) ratio for plant growth and fruiting varies depending on the plant species and environmental conditions. Generally, a C/N ratio between 10:1 and 20:1 is considered favorable for most plants. At this ratio, nitrogen is sufficiently available to support protein synthesis and growth, while carbon provides the necessary energy and structural components. A balanced C/N ratio ensures efficient nutrient cycling and optimal plant development
