Given information:
- Distance between points A and B is 5 km.
- Charlie starts at 9 a.m. from A at a speed of 5 km/hr.
- Alan starts at 9:45 a.m. from A at a speed of 10 km/hr.

Approach:
To find the time when Charlie and Alan first meet each other, we need to determine the time it takes for each person to reach point B and return to point A. Then we can compare their arrival times and find the point of intersection.

Calculations:
1. Charlie's journey:
- Distance between A and B is 5 km.
- Charlie's speed is 5 km/hr.
- Time taken by Charlie to reach B = Distance/Speed = 5/5 = 1 hour.
- Time taken by Charlie to return from B to A = 1 hour.

2. Alan's journey:
- Distance between A and B is 5 km.
- Alan's speed is 10 km/hr.
- Time taken by Alan to reach B = Distance/Speed = 5/10 = 0.5 hours = 30 minutes.
- Time taken by Alan to return from B to A = 0.5 hours = 30 minutes.

3. Time of intersection:
- Charlie starts at 9 a.m. and returns to A at 10 a.m.
- Alan starts at 9:45 a.m. and returns to A at 10:15 a.m.
- If we compare their arrival times, Charlie arrives first at 10 a.m. and Alan arrives at 10:15 a.m.
- Therefore, the first meeting time is between 10 a.m. and 10:15 a.m.

4. Calculation of exact meeting time:
- Charlie takes 1 hour to reach B, so he covers 5 km in 1 hour.
- Alan takes 0.5 hours to reach B, so he covers 5 km in 0.5 hours.
- The difference in their arrival times is 1 hour - 0.5 hours = 0.5 hours = 30 minutes.
- Charlie and Alan will meet each other halfway, so the meeting point is 2.5 km from A.
- Since Charlie's speed is 5 km/hr, he covers 2.5 km in 0.5 hours = 30 minutes.
- Therefore, Charlie and Alan will meet each other at 10:10 a.m.

Conclusion:
Charlie and Alan will first meet each other at 10:10 a.m. (option c).
