(B) The inert pair effect becomes significant for the $6^{th}$ and $7^{th}$ period $p-$block elements. Due to the poor shielding of $d$ and $f$ orbitals,the $ns^2$ electrons are held tightly by the nucleus and do not participate in bonding,making the $+1$ oxidation state more stable than the $+3$ state for $Tl$.
