C Correct answer
Explanation

The sector angle is calculated as (part/total) * 360 degrees. (3000 / 15000) * 360 = (1/5) * 360 = 72 degrees.

AI explanation

The proportion of people who like coffee is 3000 out of 15000, which simplifies to 1/5 of the total. In a pie chart, the sector angle is found by multiplying this fraction by 360 degrees. Therefore, the sector angle is (1/5) x 360 = 72 degrees.
