D. 11 : 55 am

Answer

To find the time that is 3 hours and 40 minutes before 2:30 PM, we can break the problem down into two parts: first, subtracting the hours, and then subtracting the minutes.

### Step-by-Step Solution:

1. **Start with the given time:**
The current time is 2:30 PM.

2. **Subtract 3 hours:**
- From 2:30 PM, if we subtract 1 hour, we get 1:30 PM.
- Subtracting another hour gives us 12:30 PM.
- Subtracting one more hour results in 11:30 AM.
So, after subtracting 3 hours, the time is 11:30 AM.

3. **Subtract 40 minutes:**
- We will first subtract 30 minutes from 11:30 AM.
- Subtracting 30 minutes from 11:30 AM gives us 11:00 AM.
- Now, we need to subtract an additional 10 minutes from 11:00 AM.
- Subtracting 10 minutes from 11:00 AM results in 10:50 AM.

4. **Final Result:**
Therefore, the time that is 3 hours and 40 minutes before 2:30 PM is **10:50 AM**.
