When producing monochlorobenzene using benzene chlorination, it is necessary to control the amount of chlorine used in order to reduce the formation of the byproduct dichlorobenzene. It is known that for every 100 mol of benzene, 40 mol of chlorine react; the reaction products consist of 38 mol of chlorobenzene, 1 mol of dichlorobenzene, and 38–61 mol of unreacted benzene. After separation of the reaction products, 60 mol of benzene can be recovered, with 1 mol of benzene lost. Then the total conversion rate of benzene is 【】 A、39% B、 62% C、 88% D、 97.5% D
