(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
