Solution
The Pythagoreans believed in a concept called "Musica Universalis" or "Music of the Spheres", where they associated music with the heavenly bodies - the sun, moon, and planets. They thought that these celestial bodies moved according to mathematical equations, which corresponded to musical notes and thus produced a symphony in the cosmos.
The Pythagoreans did not have the means to measure the diameter of a planet or its color. They believed that the movement of the planets, which we know today is determined by their orbits, created a celestial harmony. Therefore, they would have used the size of the orbit to determine a planet's musical note.
So, the answer to your question would be:
e. (II) only
