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

To do so, we select the labels and fields in question, proceed to the Arrange tab, sizing and ordering group and then click on the Align button.
