How does Ocean play an important role in supplying water to us

The water we consume ultimately comes from the sea: because of sunlight, water heats up and evaporates into theatmosphere, where lower temperatures transform steam into droplets, which create clouds. ... More than 97% of the water on earth is in the oceans –the rest is found in glaciers, on lands and in the ground.

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.
