Consider the following function definition:

def isPal(myStr): """ myStr is a string. Returns True if myStr is forms a palindrom, False otherwise """ temp = myStr temp.reverse if temp == myStr: return True else: return False print(isPal('anna')) This function contains several bugs. When we first call print(isPal('anna')) we get the following error message: AttributeError: 'str' object has no attribute 'reverse'

Select how to modify the code so that this error only does not occur (do not pick the solutions that fix other bugs).

a. Insert at the beginning of the block of code: myStr = list(myStr)

b. Replace temp = myStr by temp = myStr[:]

c. Replace if temp == myStr: by if temp == list(myStr):

d.

Replace temp.reverse by temp.reverse()
