The correct Answer is:
To solve the question about Stanley Miller's experiment, we need to identify the gases he used in the spark chamber to support the Oparin-Haldane hypothesis. Here’s a step-by-step breakdown of the solution: ### Step 1: Understand the Experiment Stanley Miller conducted an experiment in 1953 to simulate the conditions of early Earth and test the Oparin-Haldane hypothesis, which proposed that organic compounds could be formed from inorganic precursors under the right conditions. ### Step 2: Identify the Gases Used In his experiment, Miller used a mixture of gases that were believed to be present in the early atmosphere of Earth. The primary gases he used were: - Methane (CH4) - Ammonia (NH3) - Hydrogen (H2) ### Step 3: Analyze the Options Now, let’s look at the options provided: - A. CH3NH3H2O - B. CH4NH3H2 - C. CH4NH3Urea - D. CH4NH3Uric Acid From the analysis, we can see that option B (CH4, NH3, H2) contains the correct gases used in the experiment. ### Step 4: Conclusion Therefore, the correct answer to the question is: **B. CH4, NH3, H2** ---
