Correct Answer is : P⟶5,Q⟶2,R⟶1,S⟶4

{\P} \rightarrow 4, {\Q} \rightarrow 3, {\R} \rightarrow 1, {\S} \rightarrow 2

{\P} \rightarrow 5, {\Q} \rightarrow 2, {\R} \rightarrow 1, {\S} \rightarrow 4

{\P} \rightarrow 5, {\Q} \rightarrow 1, {\R} \rightarrow 2, {\S} \rightarrow 4

{\P} \rightarrow 3, {\Q} \rightarrow 2, {\R} \rightarrow 1, {\S} \rightarrow 5

List-I shows various functional dependencies of energy (E) on the atomic number (Z). Energies associated with certain phenomena are given in List-II.
Choose the option that describes the correct match between the entries in List-I to those in List-II.

	List-I		List-II
(P)	E∝Z2	(1)	energy of characteristic x-rays
(Q)	E∝(Z−1)2	(2)	electrostatic part of the nuclear binding energy for stable nuclei with mass numbers in the range 30 to 170
(R)	E∝Z(Z−1)	(3)	energy of continuous x-rays
(S)	E is practically independent of Z	(4)	average nuclear binding energy per nucleon for stable nuclei with mass number in the range 30 to 170
		(5)	energy of radiation due to electronic transitions from hydrogen-like atoms
