When L-erythrose is treated with NaBH 4 , ________.

L-erythrose treated with NaBH4 results in the reduction of the carbonyl group to an alcohol, forming an alditol. Since L-erythrose is a symmetrical molecule, the reduction leads to a meso compound, which is optically inactive due to its internal plane of symmetry.
