• C. the assertion is correct but reason is incorrect
• D. the assertion is incorrect but the reason is correct

Answer 1

The correct option is C

the assertion is correct but reason is incorrect

Correct reason:

• Atom is the smallest portion of matter which can take part in chemical combination.
• Atoms are not able to exist independently.
• All the atoms on the far right side of the periodic table (inert or noble gases) can exist independently because they all fulfill the octet rule.
• They don't need to form a bond to become stable.
• Hence, the correct option is (c) the assertion is correct but the reason is incorrect.
