Best answer
Right option is (a) Lead

Explanation: The maximum prescribed upper limit concentration of lead in drinking water is about 50 ppb. Drinking water gets contaminated with lead when lead pipes are used for the transportation of drinking water. Lead is a harmful substance and can cause damage in kidneys, liver, reproductive system, etc.
