B Correct answer
Explanation

The Sun contains approximately 99.8% of the total mass of the entire Solar System. This is because the Sun's mass is about 1.989 × 10^30 kg, while all the planets, asteroids, comets, and other objects combined make up only about 0.2% of the Solar System's mass. Jupiter, the largest planet, itself contains about 71% of all planetary mass, but even Jupiter is tiny compared to the Sun.
