Compounds ‘A’ and 'B' react according to the following chemical equation :

${\mathrm{A}}_{\left(\mathrm{g}\right)}+2{\mathrm{B}}_{\left(\mathrm{g}\right)}\to 2{\mathrm{C}}_{\left(\mathrm{g}\right)}$

Concentration of either ‘A’ or 'B' were changed keeping the concentration of one of the reactants
constant and rates were measured as function of initial concentration. Following results were obtained.
Choose the Correct option for this reaction.

Experi- ment	Initial concentration of $\left[\mathrm{A}\right]/{\mathrm{molL}}^{-1}$	Initial concentration of $\left[\mathrm{B}\right]/{\mathrm{molL}}^{-1}$	Initial concentration of $\left[\mathrm{C}\right]/\mathrm{mol}{L}^{-1}$
