Option B, increases
If we arrange NaC2H3O2, we will get CH3COONa. As it is dissolved in water, it dissociates into ions
Positive ion - Na+
Negative ions - CH3COO-
In chemistry, electrical conductivity is defined as the amount of ionic concentration in a solution. With dissociation of CH3COONa, the ionic concentration increases and hence the electrical conductivity also increases.
hence, option B is correct
fumikage isn't really a bird, and tsuyu does have teeth. tsuyu has a transformation quirk which still allows her to be partially human. otherwise we'd have a large frog running around. fumikage has teeth because again, he isn't a bird. his head was a quirk mixture if i'm correct.
