B Correct answer
Explanation

The Earth's axial tilt (approximately 23.5 degrees) is the primary reason for seasons. Without this tilt, the amount and intensity of sunlight received at different latitudes would remain constant throughout the year, resulting in no seasonal changes. Option A is incorrect because seasons would not exist at all, let alone have the same duration. Options C and D are incorrect because there would be no distinct summer or winter periods.
