Statement 1 : Λm for weak electrolytes shows a sharp increase, when the electrolytic solution is diluted.Statement 2 : For weak electrolytes degree of dissociation increases with dilution of solution.

Molar conductivity of weak electrolytic solution increases on dilution, because as we add excess water to increase the dilution degree of dissociation increases which leads to increase in the number of ions in the solution. Thus, Λm show a very sharp increase.
