A charged shell of radius R carries a total charge Q. Given 
as the flux of electric field through a closed cylindrical surface of height h, radius r and with its center same as that of the shell. Here, center of the cylinder is a point on the axis of the cylinder which is equidistant from its top and bottom surfaces. Which of the following option(s) is/are correct?
[

A
If h < 8R/5 and r = 3R/5 then 
= 0
= 0
B
If h > 2R and r > R then 
C
