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

List-$I$	List-$II$
$A$. $AC$ generator	$I$. Detects the presence of current in the circuit
$B$. Galvanometer	$II$. Converts mechanical energy into electrical energy
$C$. Transformer	$III$. Works on the principle of resonance in $AC$ circuit
$D$. Metal detector	$IV$. Changes an alternating voltage for smaller or greater value

Choose the correct answer from the options given below:

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