The correct answer is B.precipitation.

Here's how it works:

During lightning, the intense heat and energy cause the nitrogen gas (N₂) in the atmosphere to combine with oxygen, forming nitrogen oxides (NO and NO₂). These nitrogen oxides then react with water vapor in the atmosphere, forming nitrates (NO₃⁻). These nitrates are then carried to the Earth's surface when it rains, as they dissolve in the rainwater. This process is often referred to as atmospheric nitrogen fixation.

So, the nitrates formed during lightning fixation get to the soil through precipitation, where they become available for plants to absorb.
