**(c)**

It is given that

Hence, the greatest value of is 6

Since the least value of the modulus of a complex number is zero

is satisfied by

Therefore, the least value of is 0

__ALITER__ Here, we have to find the greatest and least of distances of all points lying inside or the circle from the point It is evident from the Fig. S.3, that the greatest distance is 6 when coincides with and the least distance is 0 when coindies with
