Given below are 2 statements: Assertion and Reason. Choose the correct option.

Assertion: When Molar conductivity for a strong electrolyte is plotted versus $$\sqrt{C}(\mathrm{~mol} / \mathrm{L})^{1 / 2}$$, a straight line is obtained with intercept equal to Molar conductivity at infinite dilution for the electrolyte and Slope equal to $$-\mathrm{A}$$. All electrolytes of a given type have the same $$\mathrm{A}$$ value.

Reason: At infinite dilution, strong electrolytes of the same type will have different number of ions due to incomplete dissociation.

A
Assertion is correct but Reason is incorrect statement.
B
Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
C
Both Assertion and Reason are incorrect statements.
D
Assertion is incorrect but Reason is correct statement.
