The Correct Option is C
Solution and Explanation
All of the factors you listed can contribute to the covalent character of a compound. The extent to which each factor contributes depends on the specific compound and its chemical properties.
The polarising power of a cation refers to its ability to pull electron density towards itself, which can result in partial covalent bonding between the cation and the anion. Similarly, the polarisability of an anion refers to its ability to be distorted by an oppositely charged ion, which can lead to partial covalent bonding.
The distortion caused by a cation also contributes to covalent character, as it can lead to the formation of partial covalent bonds between the cation and anion.
Finally, the polarisability of a cation can also play a role in covalent character, as a highly polarisable cation can form partial covalent bonds with the anion due to the distortion it causes in the anion.
Therefore, all of these factors can contribute to the covalent character of a compound, and their relative importance depends on the specific compound and its chemical properties.
Answer. A, B, C

Concepts Used:
Chemical Bonding and Molecular Structure
Such a group of atoms is called a molecule. Obviously, there must be some force that holds these constituent atoms together in the molecules. The attractive force which holds various constituents (atoms, ions, etc.) together in different chemical species is called a chemical bond.
Types of Chemical Bonds:
There are 4 types of chemical bonds which are formed by atoms or molecules to yield compounds.
- Ionic Bonds - Ionic bonding is a type of chemical bonding which involves a transfer of electrons from one atom or molecule to another.
- Covalent Bonds - Compounds that contain carbon commonly exhibit this type of chemical bonding.
- Hydrogen Bonds - It is a type of polar covalent bonding between oxygen and hydrogen wherein the hydrogen develops a partial positive charge
- Polar Bonds - In Polar Covalent chemical bonding, electrons are shared unequally since the more electronegative atom pulls the electron pair closer to itself and away from the less electronegative atom.
Factors Affecting Bond Enthalpy in Chemical Bonding:
- Size of the Atom
- Multiplicity of Bonds
- Number of Lone Pair of Electrons Present
- Bond Angle
