SN1 means Unimolecular substitution reaction, in this reaction reactant first loose the leaving group and forms carbocation(RDS)then Nucleophile will attack and reaction will complete.
The rate of reaction is depends only one 1 reactant and the rate is determined by Rate determining step.
In option A- two reactants are present, therefore it should be SN2 instead of SN1.
In option C- Wrong cleavege of bond. As Br is more electronegative it will take the electron pair, therefore this is also wrong option.
In option D- radical formation takes place due to symmetrical cleavage of bond, therefore it is radical reaction.
Option- B is the correct option, as Br will take the electron pair and most stable carbonation will form.
Answer is B.
