Which elements have the most positive and most negative electron gain enthalpy,respectively?

Match the following:

List-$I$ (Element)	List-$II$ ($\Delta_{eg}H$ in $kJ \ mol^{-1}$)
$A$. $O$	$I$. $-200$
$B$. $F$	$II$. $-349$
$C$. $Cl$	$III$. $-141$
$D$. $S$	$IV$. $-328$
	$V$. $+48$

The correct answer is:

Which of the following statements is correct?

Given below are two statements:
Statement $I$: Fluorine has most negative electron gain enthalpy in its group.
Statement $II$: Oxygen has least negative electron gain enthalpy in its group.
In the light of the above statements,choose the most appropriate from the options given below.

If the electron affinity of $Cl$ is $348 \ kJ/mol$,then how much energy is released to convert $1.0 \ g$ of $Cl$ into $Cl^-$ gas in $kJ$?

The equation used to represent the electron gain enthalpy is
