Hint: Hydrogen atoms don’t have p-shell. Oxygen atoms have a P-shell. Oxygen and Hydrogen atoms are non metal in nature . They form a special type of bond in between them in the formation of the water molecule. In octet rule all the atoms should have the ability to sustain eight electrons.
Complete step by step answer:
As we know hydrogen atoms have only s-shell. It’s nucleus is simply a proton. So no question arises that a hydrogen atom will be able to complete an octet. Hydrogen atoms cannot form octet. On the other hand an oxygen atom has both an s and p-shell. In a water molecule the oxygen atom has six electrons in the p-shell position and 2 electrons in the s-shell which is covalently shared with the two hydrogen atoms. So the Assertion is wrong. Hydrogen and Oxygen both are non metals and two non metals are always bonded in covalent manner between them . In water the oxygen atom and hydrogen atoms have covalent bonds in between them. So the Reason is also wrong.
So, the correct answer is Option D .
Note:
Covalent bond is the strongest chemical bond. The bond between a metal and a non metal can be an ionic bond or a coordinate bond. No chemical bond can be 100 percent ionic. Ionic bond is the weakest chemical bond. Examples of ionic compounds are : $NaCl,KCl,KI$ and many more.
The water molecules have hydrogen bonding with one another. Only high electronegative atoms such as $N,O$ or $F$ atoms can show hydrogen bonding. It is one of the strongest bonds known to us.
