Answer :
(a) Vitamin B3 is most polar among them . As I have shown in the image attached it has more no. of polar bonds so due to that it has high value of dipole moment than others .
Also as we know Vitamin B and C are soluble in water because of their polar nature . Other vitamin are fat soluble.
(c) : chemical formula of vitamin K3 is C11 H8 O2 .
