Many Important Resources Are Available to All People,even Those People

Many important resources are available to all people,even those people who do not contribute to them.Examples of these resources include public roads,public education,and public radio and television programming.How would a sociologist account for the fact that many people who benefit from these,either directly or indirectly,choose not to pay their fair share?

A) People believe their personal contribution (or lack of contribution) does not have much effect on the continued existence or quality of the good or service.
B) People often choose to act in their own immediate self-interests.
C) People often see no reason to incur personal costs if they do not have to.
D) All of the above.
