because it's ---------- by resonance.
O A. lower; destabilized
OB. lower; stabilized
OC. higher; destabilized
O D. higher; stabilized

If 2-iodobutane had been used to alkylate saccharin instead of iodoethane the reaction would have been
O A. slower; an achiral product
OB. faster; a racemic mixture
OC. slower; a racemic mixture
O D. faster; an achiral product
and would have produced
