A. It allows plants to use nitrogen to grow.
Explanation:
However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.
Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).
It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.
