Match the List-$I$ with List-$II$:

$A$. Carbocation	$I$. Species that can supply a pair of electrons.
$B$. Carbon free radical	$II$. Species that can receive a pair of electrons.
$C$. Nucleophile	$III$. $sp^2$ hybridized carbon with empty $p$-orbital.
$D$. Electrophile	$IV$. $sp^2/sp^3$ hybridized carbon with one unpaired electron.

Choose the correct answer from the options given below:

• A
  $A-IV, B-II, C-III, D-I$
• B
  $A-II, B-III, C-I, D-IV$
• C
  $A-III, B-IV, C-II, D-I$
• D
  $A-III, B-IV, C-I, D-II$
