(+5) A school has decided to give students cash prize if they achieve a good GPA. If GPA is higher than 3.5, the student will get $100. If GPA is higher than 3.0 but does not exceed 3.5, the student will get $50. No cash prize is awarded if GPA is 3.0 or below. Which of the following Python statements implements this cash prize system?

A.

if gpa > 3.5:

prize = 100

elif gpa > 3.0 and gpa < 3.5:

prize = 50

else:

prize = 0

B.

if gpa > 3.5:

prize = 100

elif gpa > 3.0 or gpa < 3.5:

prize = 50

else:

prize = 0

C.

if gpa >= 3.5:

prize = 100

elif gpa > 3.0 and gpa < 3.5:

prize = 50

else:

prize = 0

D.

if gpa > 3.5:

prize = 100

elif gpa > 3.0 and gpa <= 3.5:

prize = 50

else:

prize = 0

else:

print('you do not need to write the review paper')

B.

if test1 >= 90 or test2 >= 90:

print('you do not need to write the review paper')

else:

print('you need to write the review paper')

C.

if test1 < 90 or test2 < 90:

print('you need to write the review paper')

else:

print('you do not need to write the review paper')

D.

None of the code above correctly determines if you need to write a paper
