B Correct answer
Explanation

The sector angle is calculated as (part/total) * 360 degrees. Here, (30/300) * 360 = 0.1 * 360 = 36 degrees.

AI explanation

To find the sector angle in a pie chart, calculate the proportion of the specific group and multiply it by 360 degrees. Using the formula, Sector Angle = (Number of people who play cricket / Total number of people) * 360. Substituting the values gives (30 / 300) * 360 = 0.1 * 360 = 36 degrees.
