(PLS HELP) In the program below, which variable has the same scope as strA?

def usernameMaker (strFirst, strLast):
return strFirst + strLast[0]

def passwordMaker (strA, numC):
if len(strA) > 4:
answer = dogName[0:3]
return answer + str(numC)
else:
return 'xk&' + str(numC)

# the main part of your program that calls the function
username = usernameMaker ('Chris', 'Smith')
dogName = 'Sammy'
favoriteNumber = 7
password = passwordMaker (dogName, favoriteNumber)
print ("Username is ",username)
print ("Password is ",password)

Ans: strA and have the same scope
Options: (a)favoriteNumber
(b) strLast
(c) strFirst
(d) numC
