what of the planets has seasonal changes that are comparable to Earth and Mars? A. Neptune B. Uranus C. Jupiter D. Saturn

C. Jupiter

Planetary seasons are caused by two factors: axial tilt and variable distance from the sun (orbital eccentricity). Earth's orbit is nearly circular and so has little effect on climate. It's our planet's axial tilt that causes almost all seasonal changes. When the north pole is tilted toward the Sun, it's northern summer. Six months later the north pole tilts away from the Sun and we experience northern winter.

The other two planets where it is northern spring, Jupiter and Venus, have very small axial tilts - - just 3 degrees compared to Earth's 23.5 degree tilt. Seasonal changes on those planets are correspondingly small.
