(A) The correct matches are as follows:$A$. Transistors use Dry cells (Leclanché cell),where Anode is $Zn$ and Cathode is $Carbon$ $(A-III)$.$B$. Hearing aids use Mercury cells,where Anode is $Zn/Hg$ and Cathode is $HgO + C$ $(B-I)$.$C$. Inverters use Lead storage batteries,where Anode is $Pb$ and Cathode is $PbO_2$ $(C-IV)$.$D$. Apollo space ships used Hydrogen fuel cells $(D-II)$.Therefore,the correct sequence is $A-III, B-I, C-IV, D-II$.

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

List-$I$ (Applications) List-$II$ (Batteries/Cell)

$A$. Transistors $I$. Anode $- Zn/Hg$; Cathode $- HgO + C$

$B$. Hearing aids $II$. Hydrogen fuel cell

$C$. Inverters $III$. Anode $- Zn$; Cathode $- Carbon$

$D$. Apollo space ship $IV$. Anode $- Pb$; Cathode $- PbO_2$

Choose the correct answer from the options given below:

List-$I$ (Applications)	List-$II$ (Batteries/Cell)
$A$. Transistors	$I$. Anode $- Zn/Hg$; Cathode $- HgO + C$
$B$. Hearing aids	$II$. Hydrogen fuel cell
$C$. Inverters	$III$. Anode $- Zn$; Cathode $- Carbon$
$D$. Apollo space ship	$IV$. Anode $- Pb$; Cathode $- PbO_2$
