(C) The molar mass of $Na_2CO_3$ is $M_m = (2 \times 23) + 12 + (3 \times 16) = 106 \ g/mol$. The formula for Molarity $(Y)$ is $Y = \frac{X \times 1000}{M_m \times V(mL)}$. Substituting the values: $Y = \frac{X \times 1000}{106 \times 100} = \frac{X}{10.6}$. Checking option $(c)$: If $X = 1.06 \ g$,then $Y = \frac{1.06}{10.6} = 0.1 \ M$. Thus,the correct values are $X = 1.06$ and $Y = 0.1$.
