Correct Answer:
Option B —
Venus
Why the Sun Rises in the West on Venus
On most planets in our solar system, including Earth, the Sun rises in the east and sets in the west because the planets rotate prograde (counter-clockwise when viewed from above the North Pole). However, Venus is an exception due to two main factors:
Retrograde Rotation: Venus rotates on its axis in the opposite direction to most other planets (clockwise). This is known as retrograde rotation. If you were standing on the surface of Venus, this backwards spin would make the Sun appear to rise in the west and set in the east.
Extremely Slow Spin: Venus rotates very slowly. In fact, its "day" (one full rotation) lasts about 243 Earth days, which is actually longer than its "year" (its orbit around the Sun, which takes about 225 Earth days).
Note on Uranus: Uranus also has a unique rotation. It is tilted at about 98 degrees, meaning it effectively rotates on its side. Depending on the season and where you are on the planet, the Sun's path can appear very unusual, but Venus is the classic example of a consistent "West-to-East" solar cycle.
