B Correct answer
Explanation

The area of a circle is πr² where r is the radius. Given diameter is 35 cm, so radius r = 35/2 = 17.5 cm. Using π = 22/7, Area = (22/7) × (17.5)² = (22/7) × 306.25 = 962.5 cm². Option A is incorrect because it uses diameter instead of radius in calculation. Options C and D are calculation errors.
