The most suitable reagent for performing the following transformation, is 
(a)$\mathrm{LiAlH}_{4}$
(b)$\mathrm{H}_{2}$, $\mathrm{Pd}/\mathrm{C}$
(c)$\mathrm{PPh}_{3}$, $\mathrm{H}_{2}\mathrm{O}$
(d)Li, Liq. $\mathrm{NH}_{3}$
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
Staudinger reduction (PPh₃ then H₂O) converts the azide to the amine without touching the enone C=C or C=O; H₂/Pd-C would reduce the alkene, LiAlH₄ the ketone, and Li/NH₃ both.
