Answer
C.
Either I or II is sufficient
D.
Neither I nor II is sufficient
E.
Both I and II are sufficient

Answer: Option B

Solution

Answer: Option B
Solution:
From I, total number of doctors in town = (1/700 x N) , where N = total number of residents in town. But, the value of N is not known.
From II, total number of doctors in town
= (Number of wards in town) x (Number of doctors in each ward)
= 16 x 16 = 256.
