Olofins are unsaturated chain compound.

Devendra Kumar said: (Dec 18, 2018)  
Unsaturated hydrocarbons is the right answer.

Olefin, also called alkene, a compound made up of hydrogen and carbon that contains one or more pairs of carbon atoms linked by a double bond. Olefins are examples of unsaturated hydrocarbons (compounds that contain only hydrogen and carbon and at least one double or triple bond). They are classified in either or both of the following ways:

1) As cyclic or acyclic (aliphatic) olefins, in which the double bond is located between carbon atoms forming part of a cyclic (closed-ring) or of an open-chain grouping, respectively.

2. Mono Olefins, di Olefins, tri Olefins, etc. in which the number of double bonds per molecule is, respectively, one, two, three, or some other number.

It should be Option B. Agree @Answer B.

Deepak said: (Jan 24, 2020)  
I think the correct option is B.

Nirav Chavda said: (Aug 18, 2020)  
The right answer is D. Because olefins is double bond unsaturated compound not cyclic.
