To solve this problem, let's break it down step by step:

Step 1: Establish the time difference between the wall clock and the actual time
- The wall clock is 10 minutes behind the actual time when 1 hour has passed.
- Therefore, for every 1 hour that passes, the wall clock loses 10 minutes.

Step 2: Determine the time difference between the table clock and the wall clock
- The table clock is 10 minutes ahead of the wall clock when 1 hour is shown by the wall clock.
- This means that for every 1 hour shown by the wall clock, the table clock gains 10 minutes.

Step 3: Calculate the time difference between the alarm clock and the table clock
- The alarm clock is 5 minutes behind the table clock when 1 hour is shown by the table clock.
- So, for every 1 hour shown by the table clock, the alarm clock loses 5 minutes.

Step 4: Find the time difference between the wristwatch and the alarm clock
- The wristwatch is 5 minutes ahead of the alarm clock when 1 hour is shown by the alarm clock.
- Hence, for every 1 hour shown by the alarm clock, the wristwatch gains 5 minutes.

Given that all clocks are correct with the actual time at 12 noon, let's calculate the time shown by the wristwatch after 6 hours:

- After 1 hour, the wall clock is 10 minutes behind, so it shows 12:50 pm.
- After 1 hour shown by the wall clock, the table clock gains 10 minutes, so it shows 2:00 pm.
- After 1 hour shown by the table clock, the alarm clock loses 5 minutes, so it shows 2:55 pm.
- After 1 hour shown by the alarm clock, the wristwatch gains 5 minutes, so it shows 3:00 pm.

Hence, after 6 hours, the wristwatch will be 5 minutes ahead of the alarm clock, which is showing 3:00 pm. Therefore, the wristwatch will show 3:05 pm after 6 hours.

However, none of the given options match the calculated time. It seems there might be an error in the provided options or the question itself.
