A Correct answer
Explanation

Physical clocks are hardware clocks that must not only be the same but must also not deviate from real time by more than a certain amount. They have bounded drift rates. Real clocks and logical clocks are different concepts - logical clocks track event ordering without reference to real time. The question tests understanding of physical clock precision requirements.
