What role does the Sun play in planetary motion according to Kepler’s laws?
The Sun is at one focus of the elliptical orbits (first law) and provides the central gravitational force driving the equal-area sweep (second law) and period-distance relation (third law). As per NCERT, applying relevant law/formula with correct units and sign convention leads to It provides the central force. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
