Pyruvic acid Pyruvic acid on reduction with yeast gives (-) lactic acid while withwith $\ce{NaBH4}$ it reduces to  (+) lactic acid.How How?

I know this has something to do with setereoselectivitystereoselectivity. But, I don't know which one would be a correct answer.

Please help, itIt would be more helpful if you could explain a bit about stereo-selective reactions (I. I know what it is, what I want to know is, how to find which of the products will be stereochemically preferred one, just like in this question).
