A straight chain hydrocarbon has the molecular formula C8H10. The hybridisation for the carbon atoms from one end of the chain to the other are respectively sp3 , sp2 , sp2 , sp3 , sp2 , sp2 , sp and sp. The structural formula of the hydrocarbon would be
(a) CH3 - C = C - CH2 - CH = CH - CH = CH2
(b) CH3 - CH2 - CH= CH - CH2 - C = C - CH = CH2
(c) CH3 - CH = CH - CH2 - C = C - CH = CH2
(d) CH2 - CH = CH - CH2 - CH = CH - C - CH
