Answer

To determine which figure represents parents with a male child affected by a disease, follow these steps:

### Step-by-Step Solution:

1. **Identify the Symbols**: In genetic diagrams, males are typically represented by squares and females by circles. An affected individual is often indicated by a shaded symbol.

2. **Look for Parents**: The first step is to identify the parents in each figure. You should look for a male (square) and a female (circle) symbol that are connected, indicating they are the parents.

3. **Check for Children**: Next, examine the offspring represented in the figure. You need to find a male child (square) among the children.

4. **Determine Affected Status**: Look specifically for the shading of the male child. The affected male child will be represented by a shaded square.

5. **Analyze Each Option**: Go through each figure option provided:
- In the first option, check if there is a male child and if he is shaded.
- In the second option, repeat the same check.
- In the third option, look for a shaded square representing a male child.

6. **Select the Correct Figure**: After analyzing all options, the figure that shows a shaded square (indicating an affected male child) connected to a male and female parent will be your answer.

### Conclusion:
The correct answer will be the option that shows a male child (square) that is shaded, indicating he is affected by the disease.
