Four identical mechanical clocks are hanging on a wall in a room. Clock A loses 2 minutes every hour. Clock B gains 3 minutes every hour. Clock C is stopped completely. Clock D is broken and its hands spin wildly in reverse. Assuming no one touches them and they all started at the exact same correct time right now, which clock will display the correct time first?
Clock C
A stopped clock shows the correct time twice a day. The other three clocks are continuously inaccurate and will never show the correct time again unless manually reset.
