A galvanometer having a coil resistance of `100 omega` gives a full scale deflection , when a current of `1 mA` is passed through it. The value of the resistance, which can convert this galvanometer into ammeter giving a full scale deflection for a current of `10A` , is :
A. `2Omega`
B. `0.1Omega`
C. `3Omega`
D. `0.01Omega`
