- Assertion (A) is correct because the Nebular Hypothesis indeed describes the formation of planets from a rotating cloud of gas and dust surrounding a young sun.
- Reason (R) is also correct as it accurately describes the accretion process that leads to the formation of larger bodies from smaller particles.
- The reason is the correct explanation of the assertion, as it explains how the processes described in the Nebular Hypothesis occur.

Understanding the Nebular Hypothesis
The Nebular Hypothesis is a widely accepted model explaining the formation of the solar system.
Assertion (A) Explained
- The assertion states that "The Nebular Hypothesis suggests that planets formed from a rotating cloud of gas and dust around a young sun."
- This statement is true as the hypothesis outlines that a vast cloud of gas and dust, known as the solar nebula, collapsed under its own gravity, leading to the formation of the sun and surrounding planets.
Reason (R) Explained
- The reason states that "The process of accretion involved particles colliding and sticking together to form larger bodies."
- This is also true. Accretion is a fundamental process in the formation of planets where dust and gas particles collide and stick together, gradually building up larger bodies through gravitational attraction.
Connection Between Assertion and Reason
- The reason provides a detailed explanation of how the assertion is accomplished.
- The process of accretion directly supports the assertion by delineating how the rotating cloud of gas and dust leads to the formation of planets.
Conclusion
- Since both the assertion and the reason are true, and the reason correctly explains how the planets formed according to the Nebular Hypothesis, option 'A' is correct: both Assertion and Reason are true, and Reason is the correct explanation of Assertion.
This understanding reinforces the scientific narrative of our solar system's formation, highlighting the interconnectedness of cosmic phenomena.
