Explanation:
See attachment for right presentation of question
Analyzing the options:
(a): May return a negative result
This option will return a negative value if marker1 is less than marker2 because it subtracts the absolute value of marker2 from the absolute value marker1.
This literally is not different from marker1 - marker2
(b): Incorrect expression
This divides only marker2 by 60, then subtracts the quotient from marker1. This is not the expected expression.
(c) This option is correct
This correctly calculate the positive difference between marker1 and marker2 and the result is divided by 60.0 (note 60.0 not 60)
(d) & (e) Integer division
When a variable declared as double is divided by an integer variable or value, the result of the computation is not always accurate due to approximation
