Answer: Option B
Solution(By Examveda Team)
Rainfall that is acidic, possesses elevated H+ ion concentrations, and has been commonly known as ‘acid rain’.the contribution from SO2 is considerably smaller than during the 1970s, so that currently, oxidised and reduced nitrogen dominate acid deposition. Deposition of reduced nitrogen (N) compounds, e.g.NH4+, can acidify via microbial transformations in the soil and also assimilation in plants leading to acidification of the rhizospehere. Other compounds also contribute to acid deposition, e.g. hydrochloric acid (HCl)
