Question

on venus a day is equal to 243 earth days. what does this mean?
a venus takes 243 earth days to rotate once on its axis
b the length of a planet’s day is directly related to its distance from the sun
c venus takes 243 earth days to orbit the sun once
d the length of a planet’s day is inversely related to its distance from the sun

Explanation:

A planet's day is defined by its rotation on its axis. Venus taking 243 Earth days for one rotation means its day length equals this duration. Options b and d are incorrect because day length isn't directly/inversely tied to distance from the Sun; option c describes a year (orbit around the Sun), not a day.

Answer:

a. Venus takes 243 Earth days to rotate once on its axis
