Define unbalanced forces(giving

Unbalanced forces are forces whose net amount is not zero.

This can take place when two equal forces are acting in the same direction or opposite direction but with different forces.

Unbalanced forces make some change in the position of the object on which force is exerted.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
