Question 36

Match List I with List II
List-I (Species) List-2 (Maximum allowed concentration in ppm in drinking water)
A. F$$^-$$ I. < 50 ppm
B. SO$$_4^{2-}$$ II. < 5 ppm
C. NO$$_3^-$$ III. < 2 ppm
D. Zn IV. < 500 ppm
Choose the correct answer from the options given below.

For drinking water, the maximum allowed concentrations are:

$$F^- < 2\ \text{ppm}$$

$$SO_4^{2-} < 500\ \text{ppm}$$

$$NO_3^- < 50\ \text{ppm}$$

$$Zn < 5\ \text{ppm}$$

Therefore:

$$A \rightarrow III$$

$$B \rightarrow IV$$

$$C \rightarrow I$$

$$D \rightarrow II$$

Hence the correct matching is:

$${A-III,\;B-IV,\;C-I,\;D-II}$$
Hence, Option D is correct
