Hi..,
For this question ans A,B&C is absolutely correct . So if they given as all d above; v can select it but here the other option is NONE then v ll give the higher preference to NONE..
c
since it is given that it takes total days to fill is 30
and every day it fill twice of previous day
so on 29th day it was half and on 30th day it filled completely as
said twice every next day
