B Correct answer
Explanation

The clock gains 2 minutes every hour. From 12 noon Monday to 12 noon Tuesday is 24 hours, so the clock gains 2 * 24 = 48 minutes total. Thus, it will show 12:48 PM.

AI explanation

Using the uniform gain formula, we calculate the total actual hours elapsed from Monday 12 noon to Tuesday 12 noon, which equals 24 hours. Because the clock gains 2 minutes every hour, we multiply the 2-minute gain by the 24 elapsed hours to get a total gain of 48 minutes. Adding this 48-minute gain to the actual time of 12 noon results in the clock showing 12:48 PM.
