Under the usual laboratory conditions, which of the following reagents convert a ketone $R X_{2} C = O$ into the corresponding secondary alcohol $R X_{2} CH - OH$ ?

Hydride donors (

NaBH X_{4}

LiAlH X_{4}

) and catalytic hydrogenation reduce

C = O

CH - OH

. Clemmensen conditions (

Zn - Hg

/HCl) reduce the carbonyl all the way to

CH X_{2}
