If the starting material has no stereogenic centers, when carbonyl compounds are reduced with a reagent such as LiAlH4 or NaBH4 and a new stereogenic center is formed, what will the composition of the product mixture be?
 
  A. Forms a racemic mixture of the two possible enantiomers B.
  Forms more of one enantiomer than another because of steric reactions around the carbonyl
 
  C. Forms more of one enantiomer than another depending on the temperature of the reaction
  D. Forms different products depending on the solvent used
