$A$ galvanometer is used in the laboratory for the null point in electrical experiments. If,on passing a current of $6 \, mA$,it produces a deflection of $2^{\circ}$,its figure of merit is close to:

• A
  $3 \times 10^{-3} \, A/\text{div}$
• B
  $333 \, \text{div}/A$
• C
  $6 \times 10^{-3} \, A/\text{div}$
• D
  $666 \, \text{div}/A$
