The Correct Option is C
Solution and Explanation
ppm means parts per million.
So:
\[
1\text{ ppm}=1\text{ part in }10^6\text{ parts}.
\]
As a fraction:
\[
1\text{ ppm}=\frac{1}{10^6}.
\]
To convert into percentage, multiply by \(100\):
\[
\frac{1}{10^6}\times100.
\]
\[
=\frac{100}{10^6}.
\]
\[
=10^{-4}\%.
\]
\[
=0.0001\%.
\]
Therefore:
\[
1\text{ ppm}=0.0001\%.
\]
