The correct Answer is:
To solve the question "On an average a galaxy has stars," we will analyze the options provided and determine the correct answer step by step. ### Step-by-Step Solution: 1. **Understanding the Question**: The question asks for the average number of stars in a galaxy. We need to evaluate the provided options to find the correct one. 2. **Analyzing the Options**: - **Option A**: 1,000 million (which is equivalent to 1 billion) - **Option B**: 100,000 million (which is equivalent to 100 billion) - **Option C**: 100 million - **Option D**: 10 million 3. **Knowledge of Galaxies**: It is known that the average galaxy contains a vast number of stars. Research indicates that a typical galaxy, like our Milky Way, contains approximately 100 billion stars. 4. **Evaluating Each Option**: - **Option A (1,000 million)**: This is 1 billion, which is too low for the average number of stars in a galaxy. - **Option B (100,000 million)**: This is 100 billion, which aligns with the known average number of stars in a galaxy. - **Option C (100 million)**: This is also too low compared to the average. - **Option D (10 million)**: This is significantly lower than the average number of stars in a galaxy. 5. **Conclusion**: Based on the analysis, the correct answer is **Option B (100,000 million)**, which is equivalent to 100 billion stars. ### Final Answer: **B. 100,000 million** ---
