Option D

Step-by-step explanation:

I think the most effective sample to this setting would be to

Divide the city into neighborhoods. Randomly sample 10 neighborhoods. And then randomly sample 20 households from those neighborhoods.

The city is first divided into the various distinct and unique neighbourhoods, then randomly sample 10 neighborhood such that this sample is a representation of the many distinct and unique neighborhoods, which include some with large homes, some with only apartments, and others a diverse mixture of housing structures.

Then from each neighborhood, take a random sample of 20 households.

This way, your sample are a representation of the population.
