hours = int(input('Enter number of hours worked: '))

# insert input validation loop here

gross_pay = hours * 10

print('Gross pay:', gross_pay)

Suppose we want the program to ask for number of hours worked repeatedly until it is within the range of 0 to 168.

Which of the following is the best input validation loop?

	A.	while hours < 0 or hours > 168: print('ERROR: Number of hours worked must be between 0 and 168') hours = int(input('Enter number of hours worked last week: '))
	B.	while hours >= 0 and hours <= 168: print('ERROR: Number of hours worked must be between 0 and 168') hours = int(input('Enter number of hours worked last week: '))
	C.	while hours >= 0 or hours <= 168: print('ERROR: Number of hours worked must be between 0 and 168') hours = int(input('Enter number of hours worked last week: '))
	D.	while hours < 0 or hours > 168: print('ERROR: Number of hours worked must be between 0 and 168')
