The scale of a galvanometer is divided into $160$ equal divisions. The galvanometer shows full scale deflection of $16$ mA and maximum voltage is $80$ mV. Now the range is changed so that the galvanometer reads $160$ $V$. The required resistance to be connected is

  • A
    $9995 \Omega$ in series.
  • B
    $4995 \Omega$ in series.
  • C
    $9.5 \times 10^{-3} \Omega$ in parallel.
  • D
    $4.95 \times 10^{-3} \Omega$ in parallel.
