-In which flask are the molecules least polar and therefore most ideal in behavior?
A)Flask A
B)Flask B
C)Flask C
D)All are the same.
E)More information is needed to answer this.

Flask C contains $N_2$ gas, which is a diatomic molecule consisting of two nitrogen atoms. Since both atoms are the same, there is no difference in electronegativity between them, resulting in a nonpolar molecule. Nonpolar molecules have no permanent dipole moment and are therefore more ideal in behavior compared to polar molecules.
