The question refers to compounds labeled (I), (II), (III), (IV), but the actual structures are not visible/provided in the prompt.

Without the molecular structures, the dipole moment cannot be determined, because dipole moment depends on:

1. Bond polarity
2. Geometry of the molecule
3. Vector addition/cancellation of bond moments

So the answer cannot be derived from the text alone.

What would normally be done

To find the compound with the highest dipole moment, we would:

1. Draw the structures of (I), (II), (III), (IV).
2. Identify polar bonds.
3. Determine molecular shape.
4. Add bond dipoles vectorially.
5. Compare the net dipole moments.

Present issue

Since the required structures are missing, I cannot independently verify whether option A = (I) is correct.

Please provide the image or describe the four compounds so I can solve it step-by-step properly.
