The correct answer is stratified sampling.

Explanation:

In stratified sampling, the population is divided into different subgroups. The final selections are chosen proportionally from each subgroup.

In this situation, the subgroup is the block. From each block, 10 houses are randomly selected and 1 person interviewed. These are proportional between the blocks.
