Zero dipole moment is the dipole moment between two atoms being zero. It depends on the polarities of individual bonds and the geometry of the atoms.
For example CO2 , two opposing oxygen atom with carbon in the center as it’s geometry . The dipole bonds are equal in magnitude but opposite in nature. So, it has zero dipole moment.
But on the other hand water (H2O) has a oxygen atom at the top of a triangular structure while two hydrogen atoms take the place of the base sides. Here also the dipole bonds are equal in magnitude but not opposing each other. So, it has non-zero dipole moment.

Explanation:
Dipole moment is defined as the product of the magnitude of the charge separated by the distance between them. If the charge separation is zero, then the dipole moment will also be zero.
a) O2F2:
This molecule has a bent shape and is polar due to the difference in electronegativity between oxygen and fluorine. Therefore, it will have a non-zero dipole moment.
b) H2O2:
This molecule has a bent shape and is also polar due to the electronegativity difference between oxygen and hydrogen. Therefore, it will have a non-zero dipole moment.
c) MnO4:
This molecule has a tetrahedral shape with four oxygen atoms surrounding the central Mn atom. The electronegativity difference between Mn and O is negligible, and the molecule is symmetrical. Therefore, the charge separation is zero, and the dipole moment of the molecule is zero.
d) All:
As explained above, options a and b have non-zero dipole moments, while option c has a zero dipole moment. Therefore, the correct answer is option c, MnO4.
In summary, the dipole moment of a molecule depends on its shape and the electronegativity difference between its constituent atoms. A symmetrical molecule with negligible electronegativity difference will have a zero dipole moment.
