Solution

The correct option is C The atoms are smaller as one goes across a row due to the increased number of protons in the nucleus with the electrons still at relatively the same distance away.
The property of chemical bond, where shared electrons are closer to nucleus is irrelevant for ionization energy trend. Hence the statement of option C is completely irrelevant in context of given question. Hence the answer is option C

Q. Assertion :Atomic size decreases across period but increases down a group of the periodic table. Reason: Moving from left to right across a period, electrons are added one at a time to the outer energy shell. Electrons within a shell cannot shield each other from the attraction to protons, while moving down a group in the periodic table, the number of electrons and filled electron shells increases.
