On average, the number of speeding tickets issued in County X every year is three times greater than the number of speeding tickets issued in County Y during the same period. Therefore, the number of people who exceed the speed limit must be higher in County X than in County Y. Which of the following describes a flaw in the reasoning above?

A. The argument fails to take into account that the speed limit may be different in the two counties.

B. The argument fails to take into account that the number of tickets issued in County X may reflect a lower proportion of drivers overall in that county.

C. The argument fails to take into account that a single driver can receive more than one ticket in a given year.

D. The argument fails to take into account that residents of County Y may be more law-abiding overall.

E. The argument fails to take into account that residents of County X may not be aware of the speed limit in that county.

Option A:- Incorrect
The argument fails to take into account that the speed limit be different in the two different counties.

Option B:- Incorrect
The argument fails to take into account that the number of tickets issued in county X may reflect a lower proportion of drivers overall in that county. Last option to be eliminated- This would be relevant if the conclusion was "People are county X drive rashly as compared to people in county Y" or something similar to this.

Option C:- correct
The argument fails to take into account that the a single driver can receive more that one ticket in a given year.
If a single driver receive more that one ticket, then the conclusion may not be true. For example
Number of Tickets - County X= 10
Number of Tickets- County Y= 5
Number of People who got tickets in county X- 1 (Same person got ticket 10 times)
Number of people who got Ticket in county Y - 5 (all tickets to different people)
In this case, the conclusion will not be true and this option points out this flaw.

Option D:- Incorrect
The argument fails to take into account the residents of county Y maybe more law abiding overall.

Option E:- Incorrect
The argument fails to take into account that the residents of county X may not be aware of the speed limit in that county
