Pick the set correctly representing the given
P statements as true \( (\mathrm{T}) \) or false \( (\mathrm{F}) \).

(I) On heating the violet colour of \( \left[\mathrm{Ti}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right] \mathrm{Cl}_{3} \) is disappeared.
(II) Red colour of ruby is due to incorporation of octahedral chromium (III) complexes into the alumina lattice.
(III) In emerald, \( \mathrm{Co}^{+3} \) ions occurpy octahedral sites in the mineral beryl \( \left(\mathrm{Be}_{3} \mathrm{Al}_{2} \mathrm{Si}_{6} \mathrm{O}_{18}\right) \)
(IV) On substitution of water in \( \left[\mathrm{Ni}\left(\mathrm{H}_{2} \mathrm{O}\right)_{6}\right]^{+2} \) by ethylenediammine (en) then spin magnetic moment is decreased.
