Q 2633245142.     3.24 g of `Hg(NO_3)_2` (molar mass= 324) dissolved in 1000 g of water constitut.es a solution having a
freezing point of - 0.0558°C while 21.68 g of `HgCl_2` (molar mass = 271) in 2000 g of water constitutes a solution with a freezing point of -0.0744°C. The `K_1` for water is 1.86 `(K- K_g)/(Mol) `. About the state of ionization of these two solids in water it can be inferred that
A

`Hg(NO_3)_2` and `HgCl_2` both are completely ionized

B

`Hg(NO_3)_2` is fully ionized but `HgCl_2` is fully unionized

C

`Hg(NO_3)_2` and `HgCl_2` both are completely unionized

D

`Hg(NO_3)_2` is fully unionized but `HgCl_2` is fully ionized
