`CH_(3)CH_(2)CHunderset((A))((OH))CH_(2)CH_(2)CH_(3)`
`(CH_(3))_(2)Cunderset((B))((OH))CH_(2)CH_(2)CH_(3)`
`(CH_(3))_(2)Cunderset((C))((OH))CH(CH_(3))_(2)`
`CH_(3)CH_(2)CHunderset((D))((OH))CH(CH_(3))_(2)`
`CH_(3)CH_(2)CH_(2)underset((E))(CH_(2))CH_(2)CH_(2)OH`

Options

A. `B gt C gt D gt A gt E`
B. `B gt C gt A gt D gt E`
C. `C gt B gt A gt Dgt E`
D. `C gt B gt D gt A gt E`
