The color of the bands on Jupiter and Saturn are due to a. the solid rock particles that drift up from the core b. hydrogen and helium that is heated up deep inside the atmosphere c. ammonia and ammonia hydrosulfide in the atmosphere d. ice crystals in the atmosphere

Option c. ammonia and ammonia hydro-sulfide in the atmosphere

Explanation:

The color bands on Jupiter and Saturn are a result of the ammonia and ammonia hydro sulfide which condenses to form clouds in the atmosphere of the of the planets and when sunlight gets reflected from these it imparts the color to the bands of these planets.

The ammonia clouds formed in the atmosphere of these planets can be seen more clearly in Jupiter as in Saturn these bands lie at a lower altitude.
