# Acid rain contains

$\begin{array}{1 1}(a)\;HCl&(b)\;HNO_3\\(c)\;H_2SO_4&(d)\;HNO_3+H_2SO_4\end{array}$

Sulfuric acid ( $H_2SO_4$ ), nitric acid ( $HNO_3$ ), and carbonic acid ( $H_2CO_3$ ) are the major components of acid rain.
Acid rain contains $HNO_3+H_2SO_4$
Hence (d) is the correct answer.
