Answer:

The answer is: B) Bus trips are a necessity for those without cars.

Explanation:

Necessity goods like bus trips, gasoline, water & electricity (utilities), all have inelastic demands. People need them more or less on a daily basis, or for normal day to day activities. If their price rises, people are going to complain A LOT. But they are still going to buy or use them, simply because they have to do so.

The demand for bus trips is inelastic because it is a utility service. When the ridership go up, it can be said that the bus trips are a necessity for those without cars.

What happens during inelasticity of demand?

When the utility derived from a commodity remains constant, the demand for consumption of goods or services is inelastic, as the consumer keeps deriving utility from such consumption.

In the above example, it is evident that an increase in bus fares led to a decrease in bus trips of the country. But the amount of bus trips eventually went up in the next year.

This clearly indicates that a person who does not have a car has a limited option of using bus trips for commuting to different places. Until there are no alternative methods of commute, the person will continue to do bus trips.

Hence, option B; Bus trips are a necessity for those without cars due to inelastic demand of bus trips is the correct statement.
