    Correct option is C CH2​OHCH2​OH and CH2​ClCH2​Cl The products (A) and (B) are CH2​OHCH2​OH  and CH2​ClCH2​Clrespectively. CH2​=CH2​colddil.KMnO4​​ACH2​OHCH2​OH​excessPCl5​​BCH2​ClCH2​Cl​ When ethylene is treated with cold dilute potassium permanganate solution, two −OH groups are added to C atoms joined by double bond to form a vicinal diol.  Thus, it is an example of dihydroxylation.  In the next step, on treatment with phosphorous pentachloride, the −OHgroups are replaced with Cl atoms to form vicinal dichloride. Option C is correct.
