-A- b and c onlybecause energy of 3s orbital is more than 3p orbital of hydrogenatom and uncertainty principle is -x25B3-x-x25B3-p-x2265-h-xA0-

List - I	List - II
I) The electrons of same orbital differ in spin	a) Stability of half filled sublevel
II) Order of energy of orbitals is $2 s, 2 p, 3 s, 3 p, 4 s$	b) Stability of completely filled sublevel
III) Electronic configuration of $N$ is $1 s^{2} 2 s^{2} 2 p^{3}$	c) Pauli's principle
IV) Electric configuration of $C u$ is [Ar] $4 s^{1} 3 d^{10}$	d) Aufbau principle

(A) b and c onlybecause energy of 3s orbital is more than 3p orbital of hydrogenatom and uncertainty principle is △x△p≥h

(A) b and c only
because energy of 3s orbital is more than 3p orbital of hydrogen
atom and uncertainty principle is $△ x △ p \geq h$
