Answer:</h2>
Option B) Nodules.
<h2>
Explanation:</h2>
- It is impossible for plants to fix atmospheric nitrogen(nitrogen present in soil) and hence they absorb nitrogen from the soil in the form of nitrates and ammonium.
- Plant absorbs nitrogen from soil through nodules present on roots.
- In case of leguminous(pulses) plant roots of the plant form a symbiotic association with nitrogen-fixing bacteria for example- Rhizobium.
- On the other hand if nitrates is directly absorbed by the plant, it is taken up by nitrate transporters which uses a proton gradient to power the nitrate to get transported.
- Absorbed nitrogen is transferred from root to shoot by xylem.
Result: Option B) is the correct answer.
