Answer:
B. housing, transportation, and food
Step-by-step explanation:
BLS stands for "The Bureau of Labor Statistics". It is government agency operating in the United States Department of Labor.
The Bureau of Labor Statistics is conducting a survey on 30,000 households upon their spending habits as to make a record of what goods and services does a typical urban U.S. family of four spends their money on.
They are preparing a chart showing the expenditure made by a family for December 2016.
In this survey by Bureau of Labor Statistics, it is found that three-quarters of the market basket that a typical urban U.S. family of four spends on are housing, transportation, and food.
Thus the answer is B. housing, transportation, and food.
