Solution

The correct option is C $1$ M
The molar mass of NaOH is 40 g/mol.
The number of moles of NaOH is equal to the ratio of its mass to molar mass.
The number of moles of NaOH $= \frac{40 g}{40 g / m o l} = 1 m o l$
The molarity of NaOH solution is the ratio of number of moles of NaOH to total volume of solution in L.
$M = \frac{1 m o l}{1 L} = 1 M$
