Assertion: Kepler’s second law of planetary motion is also known as Kepler’s law of areas.
Reason: The line joining the planet and the sun sweeps equal areas in equal intervals of time.

The correct answer is option 'A' - Both assertion and reason are true and the reason is the correct explanation of the assertion.

Explanation:
Kepler’s second law of planetary motion states that the line joining a planet and the sun sweeps out equal areas in equal intervals of time. This law is also known as Kepler’s law of areas. Let's analyze the given assertion and reason in detail:

1. Assertion: Kepler’s second law of planetary motion is also known as Kepler’s law of areas.
This statement is true. Kepler’s second law is indeed known as Kepler’s law of areas. This law explains the relationship between the orbital speed of a planet and its distance from the sun.

2. Reason: The line joining the planet and the sun sweeps equal areas in equal intervals of time.
This statement is also true and it is the correct explanation of the assertion. According to Kepler’s second law, the line joining a planet and the sun sweeps out equal areas in equal intervals of time. This means that as a planet moves around its orbit, it covers equal areas in equal amounts of time. This implies that when a planet is closer to the sun, it moves faster and covers a larger area in a given time interval. Conversely, when a planet is farther away from the sun, it moves slower and covers a smaller area in the same time interval.

Therefore, the reason provided correctly explains the assertion, and both the assertion and the reason are true.

In conclusion, Kepler’s second law of planetary motion, also known as Kepler’s law of areas, states that the line joining a planet and the sun sweeps out equal areas in equal intervals of time. This law helps to understand the relationship between a planet's orbital speed and its distance from the sun.
