Two geometrical isomers are given by the following compound

The compounds that exhibits geometrical isomerism shows 2 types of isomers. The 2 types of geometrical isomers are known as cis and trans.

In Trans form compounds are more stable compared to cis form because of less steric hindrance.

In Acetylene dibromide double bond is present that's why acetylene dibromide is going to show geometrical isomerism.

When a carbon has four different chemical groups attached it is asymmetric. 

Hence, option( D) acetylene dibromide is correct answer.
