Correct Answer: Correct answer is: (C) Sunlight.

Exam Relevance: AP Environmental Science, GRE, GATE, MCAT

Difficulty: Easy

Concept notes: Renewable energy sources are those that can be replenished naturally within a short period of time and are not depleted when used. Sunlight is a prime example of a renewable energy source because it is abundant, constantly available, and does not get depleted when harnessed for energy.

Common Mistakes: A common misunderstanding is that fossil fuels like oil and coal are renewable because they are naturally occurring. However, these resources take millions of years to form and are considered non-renewable because they cannot be replenished within a human timescale.

Explanations: Sunlight is a renewable energy source because it is naturally replenished and available in abundance. Unlike oil and coal, which are finite and take millions of years to form, sunlight is continuously available and can be harnessed without depleting the resource.

Option Analysis:

Option A: Oil is a non-renewable resource because it takes millions of years to form and cannot be replenished within a human timescale.
Option B: Coal is also a non-renewable resource for the same reason as oil; it takes millions of years to form and cannot be replenished quickly.
Option C: Sunlight is a renewable resource because it is continuously available and can be harnessed without depleting the resource.
