Sediment settles at the bottom of the ocean floor

As you have read, sediments cover the deep ocean floor, sometimes in layers thick enough to bury abyssal hills. ... These shells are the remains of tiny floating protists and animals found living in the mixed layer at the ocean surface. When these organisms die, their shells settle to the bottom.

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.
