Show answer & explanation
Correct answer: C
To determine the correct option, evaluate each statement independently.
Statement I: The exosphere is the outermost layer of Earth's atmosphere. This is correct as it lies above the thermosphere and merges with space.
Statement II: The thermosphere extends from approximately 80 km to 400 km above Earth's surface. This is accurate based on atmospheric layer definitions.
Since both statements are correct, the option indicating both I and II is the correct choice.
