Mole of NaOH=3
Weight of NaOH =$3\times 40g$
$\Rightarrow 120g$
Weight of solvent =1000g
$\therefore$ weight of solution =$1000+(3\times 70)$
$\Rightarrow 1120g$
$\therefore$ Volume of solution =$\large\frac{1120}{1.110}$$ml$
$m=\large\frac{3/1120}{1.110\times 1000}$
$\Rightarrow 2.9732$
Hence (a) is the correct option.
