Solution

The correct option is A Potassium and Calcium
  • Potassium and calcium are elements that are essential for various activities in the body.
  • The common function of both elements is their involvement in muscle contraction.
  • There are calcium ions which bind to the troponin and tropomyosin and helps in muscle contraction.
  • The potassium ions are responsible for the transmission of the impulses to allow the contraction of muscles.
Thus, the correct answer is option A.
