Which of the following statements is not correct?

List-$I$ shows reactions involved in the metallurgy of $Pb$ (lead) and List-$II$ shows the names of the processes. Match List-$I$ with List-$II$ and select the correct code for your answer.

List-$I$	List-$II$
$(P) \ PbS + 2PbO \xrightarrow{\Delta} 3Pb + SO_2 \uparrow$	$(1) \ \text{Smelting}$
$(Q) \ PbS + \frac{3}{2}O_2 \xrightarrow{\Delta} PbO + SO_2 \uparrow$	$(2) \ \text{Self reduction}$
$(R) \ PbCO_3 \xrightarrow{\Delta} PbO + CO_2 \uparrow$	$(3) \ \text{Calcination}$
$(S) \ PbO + C \xrightarrow{\Delta} Pb + CO \uparrow$	$(4) \ \text{Roasting}$

Consider the following statements:
$(a)$ When the lead-silver alloy is rich in silver,lead is removed by the cupellation process.
$(b)$ Froth flotation can be applied for non-sulphide ores also using a suitable activator.
$(c)$ $PbSO_4 + H_2SO_4$ electrolyte is used for the refining of $Pb$ by electrolysis.
$(d)$ Any metal will not reduce the oxide of other metals which lie above it in the Ellingham diagram.
Using $'T'$ for true and $'F'$ for false statements in the given sequence,select the correct set of code.

$B$. Electrolytic cell	$II$. Aluminum
$C$. Blast furnace	$III$. Silicon
$D$. Zone Refining furnace	$IV$. Copper
