While there are some exceptions, most plants cannot obtain nitrogen directly from the air and typically require it in the form of soil nutrients or fertilizers. Option B is incorrect, as while roots do play a role in nutrient acquisition, they do not provide the nitrogen required for plant growth. Option C is also incorrect, as while lightning can contribute to nitrogen fixation, it is not the leading cause of nitrogen availability in soil.
