Solution

The correct option is B Statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1
B and C from their stable halides as $B X_{3}$ and $C X_{4}$ , while Tl and Pb produce their stable halides as TiX and $P b X_{2}$ . Also both $P b X_{4}$ and $T l X_{3}$ are strong oxidizing agent. Due to inert pair effect, the +2 oxidation state of Pb is more stable than +4 oxidation state. Hence, +2 oxidation state is the stable oxidation state and +4 oxidation state acts as strong oxidizing agent.
$P b^{4 +} + 2 e^{-} \to P b^{2 +}$
$P b^{2 +} > P b^{4 +}$
Similarly, due to inert pair effect, the +1 oxidation state of Ti is more stable than +3 oxidation state. Hence, +1 oxidation state is the stable oxidation state and +3 oxidation state acts as strong oxidizing agent.
$T l^{3 +} + 2 e^{-} \to T l^{+}$
$T l^{+} > T l^{3 +}$ (due to inert pair effect).
Hence, statement-1 is true, statement-2 is true and statement-2 is NOT the correct explanation for statement-1
