Choice C is the correct answer. The question asks students to select the relevant information from the table to compute the percentage of voters for each age group in the table and then compare the percentages to identify the largest one, which is the percentage for the age group in choice C. Of the 600 total people in the 55–74 age group, 431 reported that they had voted, which represents 71.8% of the people in the 55–74 age group. This is the greatest percentage of reported voters from among the four age groups.

Choice A is not the correct answer. The question is asking for the age group with the greatest percentage of voters. This answer reflects the age group with the smallest percentage of voters. This group’s percentage of voters is 48.1%, or  303630 , which is less than that for the 55–74 age group.

Choice B is not the correct answer. The question is asking for the age group with the greatest percentage of voters. This answer reflects the age group with the largest number of voters, not the largest percentage. This group's percentage of voters is 63.4%, or  471743 , which is less than that for the 55–74 age group.

Choice D is not the correct answer. The question is asking for the age group with the greatest percentage of voters. This answer reflects the age group with the smallest number of voters, not the largest percentage. This group’s percentage of voters is 70.1%, or  124177 , which is less than that for the 55–74 age group.
