Verified by Experts

The correct Answer is:
A
The bond moments para to each other cancel due to their opposite directions. The other two groups are meta to each other at an angle of `120^(@)`.
`therefore" Dipole moment, "mu=sqrt(mu_(2)^(1)+mu_(2)^(2)+2mu_(1)mu_(2)costheta)`
where `mu_(1)=mu_(2)=1.5D`
`therefore" "mu=sqrt((1.5)^(2)+(1.5)^(2)+2(1.5)(1.5)cos120^(@))=1.5D`
