Correct Answer: (a) 60 minutes
Solution:As of April 2022, the total duration of a hockey match at the international level is 60 minutes, divided into four quarters of 15 minutes each. There is a halftime break of 10 minutes between the second and third quarters. If the match ends in a tie, it may be followed by a penalty shoot-out to determine the winner. However, the rules and regulations may differ at different levels of competition, such as domestic or junior matches, where the match duration and other rules may be different.
