The correct statement(s) for the following reactions is(are): 

${\mathrm{CH}}_3-\mathrm{C}\equiv \mathrm{C}-{\mathrm{CH}}_3\stackrel{{\mathrm{H}}_2/\mathrm{Pd}/{\mathrm{CaCO}}_3}{\to }\left[\mathrm{M}\right]\stackrel{{\mathrm{Br}}_2/{\mathrm{CCl}}_4}{\to }\left[\mathrm{N}\right]$

${\mathrm{CH}}_3-\mathrm{C}\equiv \mathrm{C}-{\mathrm{CH}}_3\underset{\left[1\mathrm{eq}\right]}{\overset{{\mathrm{Br}}_2/{\mathrm{CCl}}_4}{\to }}\left[\mathrm{O}\right]\stackrel{{\mathrm{H}}_2/\mathrm{Pd}}{\to }\left[\mathrm{P}\right]$

Products P and N are identical

(P and N) and (M and O) are pair of enantiomers

M will be the cis-alkene where as O will be the trans-alkene

(P and N) and (M and O) are pair of diastereomers
