A student writes general characteristics based on the given mechanism as:
$(a)$ The reaction is favoured by weak nucleophiles
$(b)$ $R^ \oplus$ would be easily formed if the substituents are bulky
$(c)$ The reaction is accompained by recemization
$(d)$ The reaction is favoured by non-polar solvents.
