Answer : (a) option is correct, i.e. S,S,S,S is correct option.

explanation;

R>lll change is © Roche COD -R best will chory s at A anticlockwise, lowest point priority group is on hashed Illne, therefore it will be s at B, anticlockwise rotation, towest priority group is on na lire, therefore, it will be 1 at , clockwise, it should be R but will change conformation to is because lowest priority group is not on has had line. o clockwise, it should be R, but will change conformation to s because lowest priority group is not on hashed line
