Answer 1

c. Survey a random sample of persons within each geographic region of the city.

Explanation:

Since the government intends to conduct the survey on a sample of the city residents. The sample must be random and a true representation of those who live in the city. It is therefore important that the survey is carried out on a random sample of persons within each geographic region of the city.

All other options are not true representation of the city's population.
