In an electrolyte,$3.2 \times 10^{18}$ bivalent positive ions drift to the right per second,while $3.6 \times 10^{18}$ monovalent negative ions drift to the left per second. Then the current is:

  • A
    $1.6 \, A$ to the left
  • B
    $1.6 \, A$ to the right
  • C
    $0.45 \, A$ to the right
  • D
    $0.45 \, A$ to the left
