Hope you and your family are well in this pandemic. The question
asked by you is to convert an alkene to a diol.
The reaction can be generally thought as-
Now, here the stereochemistry is also important as the the reactant is a cyclohexene derivative. What you suppose to know and have to verify from the mechanism is that the stereochemistry of the diol in the product is syn.
Why is is syn ?
This is evident from the mechanism.
The five memberred Transition state formed has to be cis w.r.t the
double bond. A five memberred trans geometry is not possible. This
is true for any reaction you will encounter. A trans five memberred
ring is either not possible or very very unstable.
So, the correct answer here is 'c' as the two OH groups are syn
w.r.t each other (both above or both below).
