(C) 12 p.m. to 7 p.m.
(D) 7 p.m. to 9 p.m

 from the load curve it is obtained that during early morning demand is always low. around 5 a.m. it starts increasing and around 9 a.m. load reaches a high value and remains almost constant till evening except for some dip during lunch hours. the load again starts increasing in evening hours and reaches its peak around 7 to 9 p.m.
