vhnd needs check for entire window, correct image for condition four

Condition Four needs different images depending on what condition it is.

End of the window conditions (at 3, 6, 9 etc months) needs to be checked if vhnd didn't happen in the selected month but happened at one of the months of the whole window (including previous 3 months). (e.g.) For exclusive_breastfed, it could be false if VHND happened at any one month in previous 6 months and it was False.
