Mass % of $H_2SO_4=29\%$
(i.e) 100g solution contains 29g $H_2SO_4$
Let the density of solution (in g/ml) is d
Molarity of solution=$\large\frac{\text{Moles of }H_2SO_4}{\text{Volume of solution(ml)}}$$\times 1000$
$\large\frac{\Large\frac{29}{98}}{\Large\frac{100}{d}}$$\times 1000=3.60$
Hence (c) is the correct answer.
