Solution

The correct option is A 2
Molarity is defined as number of moles of solute present in one litre of solution.

M = $\frac{N u m b e r o f m o l e s o f s o l u t e}{V o l u m e o f s o l u t i o n i n l i t r e s}$

Given, Number of moles = 2
Volume of solution = 1 L

M = $\frac{2}{1}$ = 2 M
