The task is to identify the major products from two reactions: one involving a substituted benzene and the other a complex polycyclic compound. The correct answer identifies the structures of the products A and B, which are 4-methyl-1-phenylpent-3-en-1-ol and 2,3,4,6,7,8-hexamethyl-5,9,10,11-tetrahydro-1H-benzo[3,4]azuleno[1,8,7,6-cdef]fluorine, respectively."}
