6. A galvanometer has a resistance of 99 ohms and deflects full scale when a current of 10−3 ampere passes through it. In order to convert this galvanometer into an ammeter with a full-scale deflection of 0.1 ampere, one should connect a resistance of
(A) 1Ω in series with it
(B) 901Ω in series with it
(C) 9,900Ω in series with it
(D) 1Ω in parallel with it
(E) 9,900Ω in parallel with it
