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.
