Epoxide

d i think

ya but why does NaOH have more preference to act as nucleophile when water is solvent and is present in larger qty?

ya but nucleophilicity of water molecule is very low it cant break epoxide ring if there would ve been a better nu as solvent then the major product would ve been changed

i think its c

pavan - ans is d

therefore the answer is B according to the SN₁ mechanism in case of a 3° carbocation formation!!!!!!!!!

cheers!!!!!!!!
