(i)
(ii)
(iv) (a) in Figure (iv) is the largest.
(b) in Figure (iii) is the least.

Solution:
Ans. Correct option : (d)
Explanation: Electric flux, through the closed surface (or space) depends only on the charge enclosed inside the surface. Here, charges inside all figures are same. So, electric flux will remain same.
