Substance 'A' is exposed to $600\,\mathrm{nm}$, $100\,\mathrm{W}$ light source for $6626\,\mathrm{s}$, with $50\%$ of the incident light being absorbed. 'A' decomposes according to the reaction $A \rightarrow 2B$. As a result of irradiation, $0.2\,\mathrm{mol}$ B is produced. The quantum yield of the reaction is closest to
