A

2

B

4

C

6

D

8

Answer

8

Explanation

Solution

The given structure has three double bonds whose each carbon atom is differently substituted hence number of geometrical isomers will be 2n=23?=8,2^{n}=2^{3 ?} =8, where n is the number of double bonds whose each carbon atom is differently substituted.
