Answer:
Option(B)
Providing people with clean, safe housing will help improve society.
Step-by-step explanation:
The passage clearly states that if we provide the laboring classes which are the lower classes living in poverty with better facilities like improved ventilation and other home facilities like clean and safe housing they will suffer less and will not be lured to committing a crime at younger age in order to fulfill their needs which is called premature mortality.
Hence crime rate will decrease and society will be better.
