How does the formation of cyanohydrins from ketones potentially lead to the creation of chiral centers?

Cyanohydrin formation involves a radical mechanism that does not affect chirality.

Cyanohydrin formation always preserves the original chirality of the ketone without creating new chiral centers.

The ketone undergoes racemization, resulting in a mixture of enantiomers without new stereocenters.

The addition of a cyanide ion to a prochiral ketone creates a new stereocenter at the carbonyl carbon.
