$A$ galvanometer is used in a laboratory for detecting 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 (each division is $1^{\circ}$):

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