Reactant A gives product B or C

The possible reagents are:

(I) $2\mathrm{Na}/\mathrm{liq}.{\mathrm{NH}}_3$

$\text{ (II) }{\mathrm{H}}_2/\mathrm{Pd}/{\mathrm{CaCO}}_3\text{ (quinoline) }$

$\text{ (III) }2{\mathrm{H}}_2/\mathrm{Pd}/\mathrm{C}$

The correct statement with respect to the above conversion is/are:

• A

  B is obtained on treatment with reagent (I)

• B

  C and B are obtained on treatment with reagent (II)

• C

  C is obtained on treatment with reagent (I)

• D

  C is obtained on treatment with reagent (II)
