The answer is a)1A. Reason: Moving across a period, the number of protons increase while the number of electrons don't really change that much. As the protons increase, more electrons are pulled closer to the nucleus, thereby decreasing the atom. Because of this, the atomic radius decrease going across a period from left to right. hope this helps!
