The correct answer is B) observation.
Among the four methods, the method of data collection that is involved when an individual counts the number of vehicles passing designated locations on the Los Angeles freeway system is observation.
When researchers use the method of observation to collect information, this means that a person acts as the observer, he or she is physically in the location to observe the phenomena.

Part of Question completed :
Which basic principle of individual choice does Charles's plan illustrate that his wife's advice does not?
Many decisions are made on the margin.
People usually exploit opportunities to make themselves better off.
Resources are scarce.
All costs are opportunity costs.
Answer:
All costs are opportunity costs
Explanation:
All choices have opportunity costs. If Charles decides to swim, he gives up the time that he could have spent biking or running. The opportunity cost of an hour of swimming is therefore an hour of biking or running, whichever he believes has most value as an alternative which could justify the sacrifice of one hour for swimming alone. There is no information on the value of an extra hour swimming however so we cannot determine whether it is best for Charles to spend time equally on all sports or otherwise.
