Answer:
Replace the comment with:
(c) double hours = Math.abs (marker1 - marker2) / 60.0;
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

Answer:
The correct code for this question:
g=float(input("Enter your English test grade:")) #take input from user.
#check conditions
if (g>=100 and g<=90):
print ("A")
#g greater then equal to 100 and less then equal to 90.
if (g>=89 and g<=80):
print("B")
#g greater then equal to 89 and less then equal to 80.
if (g>=79 and g<=70):
print("C")
#g greater then equal to 79 and less then equal to 70.
if (g>=69 and g<=65):
print("D")
#g greater then equal to 69 and less then equal to 69.
if(g<=64):
print("F")
#g less then equal to 64.
else:
print ("Not a grade")
#not a grade or fail.
Explanation:
In this program, we use to take a value from the user and check the value from the various conditions. To check all the condition we use if-else statement and AND operator that check to the range to together.
If -else is a conditional operator. In that, If block is used to check the true part and else part takes false value, and AND is a logical operator that check the two range together
