Substance 'A' is exposed to 600 nm, 100 W light source for 6626 s, with $50 \%$ of the incident light being absorbed. 'A' decomposes according to the reaction A → 2B . As a result of irradiation, 0.2 mol B is produced. The quantum yield of the reaction is closest to
(a)$6 \times 10^{6}$
(b)$6 \times 10^{-4}$
(c)$6 \times 10^{-2}$
(d)6
