Verified By Collegedunia
The Correct Option is C
Solution and Explanation
According to the CPCB ambient noise standards, the permissible noise limit for residential areas is
\[
55 \text{ dB (day)}
\]
and
\[
45 \text{ dB (night)}.
\]
Hence,
\[
\boxed{45\ \text{dB}}
\]
is the correct answer.
Therefore,
\[
\boxed{(C)}
\]
