Answer

Brief Explanations:

In a stratified random sample, the population is divided into subgroups (strata), and then samples are randomly selected from each subgroup. Here, the city is divided into zones (sub - groups) and 5 households are randomly chosen from each zone. In a simple random sample, every individual in the population has an equal chance of being selected without dividing the population first. In a cluster random sample, entire groups (clusters) are randomly selected. In a systematic random sample, individuals are selected at regular intervals from an ordered list.

Answer:

C. stratified random sample
