a. a pie chart that shows the total number of americans who designated their mobile phone as their primary home phone in 2014 versus the total number who did not.

b. a bar graph that shows the percentage of americans who used their landline as their primary home phone from the years 2004 through 2014.

c. a line graph that shows the percentage growth of americans who designated their mobile phone as their primary home phone from the years 2000 through 2010.

d. a line graph that shows the number of americans who designated their mobile phone as their primary home phone from the years 2004 through 2014.

Explanation:

The claim is about the number of Americans designating mobile phones as primary home phones quadrupling over 10 years. Option D uses a line graph (good for showing trends over time) to display the number from 2004 - 2014 (a 10 - year period), directly addressing the number and time frame of the claim. Option A compares 2014 with non - users, not growth over time. Option B focuses on landlines, not mobile phones. Option C shows percentage growth from 2000 - 2010 (not 10 years matching the claim's time frame) and uses percentage instead of number.

Answer:

D. A line graph that shows the number of Americans who designated their mobile phone as their primary home phone from the years 2004 through 2014.
