Osmotic pressure of urea solution is 380 mm at a temperature of \[10{}^\circ C\]. The solution is diluted and the temperature is raised to \[30{}^\circ C\] and the osmotic pressure is found to be 122 mm. The extent of dilution will be:

A) \[{{\text{V}}_{\text{final}}}\,\text{=}\,\text{4}{{\text{V}}_{\text{initial}}}\]                       

B) \[\text{3}{{\text{V}}_{\text{final}}}\,\text{=}\,10{{\text{V}}_{\text{initial}}}\]

C) \[{{\text{V}}_{\text{final}}}\,\text{=}\,5{{\text{V}}_{\text{initial}}}\]                     

D) \[{{\text{V}}_{\text{final}}}\,\text{=}\,2{{\text{V}}_{\text{initial}}}\]
