## Core Concept
The question involves calculating the number of deaths due to accidents in a city, given that 10% of total deaths are caused by accidents and there are 500 total deaths reported. This requires a simple percentage calculation.

## Why the Correct Answer is Right
To find 10% of 500, we multiply 500 by 0.10. This calculation yields 50 deaths due to accidents. Therefore, the correct statement is that there are 50 deaths due to accidents.

## Why Each Wrong Option is Incorrect
- **Option A:** Without the actual statement provided, we cannot directly assess its accuracy. However, any option not stating "50 deaths due to accidents" would be incorrect based on our calculation.
- **Option B:** Similarly, without the specific details of Option B, we assume it's incorrect if it does not align with 50 deaths due to accidents.
- **Option C:** This option is also incorrect for the same reason, assuming it does not correctly represent 50 deaths due to accidents.
- **Option D:** Given that the correct answer is indeed related to the calculation of 50 deaths, any other numerical value or incorrect statement would be wrong.

## Clinical Pearl / High-Yield Fact
