Explanation
The prompt cuts off after "The distribution of IQ scores" - it should specify what we're looking for. Based on standard IQ testing knowledge, the distribution IS approximately normal (bell-shaped), centered at 100 with standard deviation 15. Option A is correct. Option B is incorrect - most people score between 85-115 (one SD from mean), not 80-100. Option C is incorrect - there's no significant average IQ difference between genders. Option D is incorrect - the curve falls off gradually, not abruptly, following normal distribution properties.
