Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.

Such devices are usually considered as catheters or venous access ports, as they permit regular access to the veins without application of deep needle sticks.
All the CVADs require a dressing immediately post insertion of the device to reduce the threat of infection. It requires a dressing surrounding the entrance to the tunnel of the skin unless and until the wound gets healed. This can take about 10 to 14 days based on the condition of the patient.
If a population eventually is too large for the available resources, the first thing that would happen is competition resources between individuals in a given population. The most fit will be the ones who will survive. The predator of the new dominating population also increases and the cycle continues — but eventually the population balances itself naturally (if not intervened by humans).
