B Correct answer
Explanation

At the equator, you weigh about 3% less than at the poles due to two factors: centrifugal force from Earth's rotation pushes you outward, and the equator is farther from Earth's center (about 21 km greater radius) where gravitational pull is weaker. This difference is measurable but not noticeable in daily life.
