Explanation

Choice B is correct. It's given that there are $250$ trees in a park and of these trees, $6 percent sign$ are birch trees. The number of birch trees in the park can be calculated by multiplying the number of trees in the park by $StartFraction 6 Over 100 EndFraction$ . Therefore, the number of birch trees in the park is $250 left parenthesis StartFraction 6 Over 100 EndFraction right parenthesis$ , or $15$ .

Choice A is incorrect. This is the percentage of trees in the park that are birch trees, not the number of birch trees in the park.

Choice C is incorrect. This is $30 percent sign$ , not $6 percent sign$ , of $250$ .

Choice D is incorrect and may result from conceptual or calculation errors.
