Asubstance with a definite shape and volume is a of matter.

solid

Explanation:

Solid  involves the state in which matter has a definite shape and volume. In that respect, solids can be crystalline, which means that the atoms or molecules are arranged in a repeating pattern of rows, like iron, diamond and ice. Solids can also be amaorphous, which are constituted by atoms or molecules in no organized pattern, such as rubber and wax.

hope you got the answer

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.
