Answer:

Correct Answer: 6. (a)

Solution:

  1. Reducing agents like $LiAlH _4, NaBH _4$, i.e. complex hydrides usually does not affect olifenic or $\pi$-bonds. Thus, if $NaBH _4$ is applied to a compound like $\underset{OH}{ }$ then its $>C=O$ bond will be reduced only and we get final product.

Thus, option (a) is correct answer.
