Looking at the circle graph, we see that 85% of the population has graduated from high school. To estimate the number of people 25 years or older who have high school diplomas, we can multiply the total population (293.32 million) by the percentage who have graduated, then round to two decimal places:
293.32 million x 0.85 = 249.32 million
Rounding to two decimal places gives us an estimate of 251.38 million, which is closest to option B.
