which of the following functions finds the inverse of a mod m using brute force. if there is no inverse, it should return None

returns Inverse of a od de inverse(a,m) for i in range(n): if (a 1) 11 return return None o 1 3 returns inverse of a mod def inversela, n): it asm= 1: return None for i in range(m): if (asi) *.=1 return 1 returns inverse of a mod m def inverse(a,m): for 1 in range(a): if (mei) sa = 1: return i return i returns Inverse of a mod def inverse(a,m): If Sam 1: return 1 for i in range(m): if (axi) i = 1: return 1-1 19 return None
