A volume of 135 mL of benzene was treated with excess Cl₂ and AlCl₃ to yield 50 mL of chlorobenzene. Given the atomic weights of C 5 12.0, H 5 1.00, and Cl 5 35.5, and the densities of benzene, 0.78 g mL^-1, and chlorobenzene, 1.10 g mL^-1, the percent yield is closest to 

(a) 15; 

(b) 26; 

(c) 35; 

(d) 46; 

(e) 55.
