The extra stability of half-filled subshell is due to :
(A) Symmetrical distribution of electrons
(B) Smaller coulombic repulsion energy
(C) The presence of electrons with the same spin in non-degenerate orbitals
(D) Larger exchange energy
(E) Relatively smaller shielding of electrons by one another
Identify the correct statements

The correct statements from the following are :
(A) $$Tl^{3+}$$ is a powerful oxidising agent
(B) $$Al^{3+}$$ does not get reduced easily
(C) Both $$Al^{3+}$$ and $$Tl^{3+}$$ are very stable in solution
(D) $$Tl^+$$ is more stable than $$Tl^{3+}$$
(E) $$Al^{3+}$$ and $$Tl^+$$ are highly stable

Given below are two statements :
1 M aqueous solution of each of $$Cu(NO_3)_2$$, $$AgNO_3$$, $$Hg_2(NO_3)_2$$; $$Mg(NO_3)_2$$ are electrolysed using inert electrodes.
Given : $$E_{Ag^{+}/Ag}^{\theta} = 0.80V, E_{Hg_{2}^{2+}/Hg}^{\theta} = 0.79V,$$
           $$E_{Cu^{2+}/Cu}^{\theta} = 0.24V$$ and $$E_{Mg^{2+}/Mg}^{\theta} = -2.37V$$
Statement (I) : With increasing voltage, the sequence of deposition of metals on the cathode will be Ag, Hg and Cu
Statement (II) : Magnesium will not be deposited at cathode instead oxygen gas will be evolved at the cathode.
