We can use the formula for the sum of the interior angles of a polygon, which is (n-2) x 180 degrees, where n is the number of sides in the polygon.
Given that the sum of the interior angles is 900°, we can set up the equation:
(n-2) x 180 = 900
Simplifying this equation, we get:
n - 2 = 5
n = 7
Therefore, the polygon has 7 sides, and the answer is B.
