The correct options are
B All planets revolving around the Sun have different orbital planes.
C At different points of time in the year, the distance between the Earth and the Sun is different.
The Earth revolves around the Sun in an elliptical orbit, not in a circular orbit. Hence, at different points of time in the year, the distance between the Earth and the Sun is different.
Venus is closer to the Sun as compared to the Earth. Hence, it has a smaller orbit than the Earth.
