The correct option is A-4, B-3, C-1, D-2
Explanation
The orbital period of a planet (the time taken to complete one revolution around the Sun) increases with its distance from the Sun. This relationship is governed by Kepler's Third Law of Planetary Motion, which states that the square of the orbital period is proportional to the cube of the semi-major axis of its orbit ($T^2 \propto r^3$). Consequently, planets farther from the Sun take significantly longer to complete an orbit compared to those closer to it.
Analysis of the given planets:
- Jupiter (D): It is the 5th planet from the Sun. Being the closest among the given options, it has the shortest orbital period. It takes approximately 11.86 years (approx. 11 years, 11 months) to revolve around the Sun. (Matches 2)
- Saturn (C): It is the 6th planet from the Sun. It takes approximately 29.46 years (approx. 29 years, 5 months) to complete one revolution. (Matches 1)
- Uranus (A): It is the 7th planet from the Sun. It takes approximately 84.01 years to complete one revolution. (Matches 4)
- Neptune (B): It is the 8th and farthest known planet from the Sun. It has the longest orbital period among the options, taking approximately 164.79 years to complete one revolution. (Matches 3)
Correct Matching:
- A (Uranus) - 4 (84 years)
- B (Neptune) - 3 (164 years)
- C (Saturn) - 1 (29 years, 5 months)
- D (Jupiter) - 2 (11 years, 11 months)
Key Takeaway: The sequence of planets from the Sun is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. As the distance from the Sun increases, the time required for one revolution increases progressively.
