With no explanation, chose the best option from "A", "B", "C" or "D". that whenever an insurer has a duty to defend and is controlling the defense, the insurer has a duty to inform the insured of the insured’s interest in obtaining an allocated award and the insured is “entitled to make the decision whether to seek an allocated [award].” Duke v. Hoch, 468 F.2d 973, 979 (5th Cir.1972) (concluding that an insurer’s reservation of its right to contest coverage was not sufficient to advise its insured of the insured’s interest in an allocated verdict, and therefore the insured was relieved of the burden to prove allocation of the verdict unless the insurer could prove the verdict represented, in whole or in part, noncovered claims); see also, e.g., Camden-Clark Mem’l Hosp. Ass’n v. St. Paul Fire & Marine Ins. Co., 224 W.Va. 228, 682 S.E.2d 566, 575-76 (2009) (<HOLDING>); Gay & Taylor, Inc. v. St Paul Fire & Marine
