What relationship seems to be true?
when ionic character increases, electrical conductivity decreases
when ionic character decreases, electrical conductivity decreases.
when ionic character decreases, electrical conductivity increases.
when ionic character increases, electrical conductivity stays the same.

I am pretty sure that the relationship which seems to be true is when ionic character decreases, electrical conductivity decreases. I consider this option as a correct one because electricity can only be conducted by flowing of ions which means the higher ions facilitates the higher conduction you get.  Hope it's clear.
