Answer: The correct answer is "current".
Explanation:
The electric shock happens when the circuit is complete with respect to ground. In this case, the electric current enters from one point through the conductor and exits from the another point.
In case of bird sitting on the electrical wire of the electric pole, it does not get electric shock as the circuit is not complete with respect to the ground. That is why the electric current does not flow through its body.
Therefore, an electrical shock happens when electric current enters the body at one point and leaves through another.

Further Explanation:
The rate of flow of electric charges is known as electric current. It is generally represented by I. It passes through the substances that carry current carriers in them. The electrons are said to be the current carriers. Electrons are the negatively charged subatomic particles which along with the atomic nucleus comprise the atom. The SI unit of electric current is Ampere or Coulomb per second. One Ampere is defined as the rate of flow of one-coulomb charge in unit time. The instrument used to measure electric current is called ammeter.
The formula to calculate the electric current is as follows:
[tex]{\text{I}} = \dfrac{{\text{Q}}}{{\text{t}}}[/tex]
Here,
I is the electric current.
Q is the amount of charge in Coulomb.
t is the time in seconds.
Conductors are the substances that permit electric current to flow through them. Metals are good conductors of heat and electricity as these have free charge carriers that move randomly and produce current. Insulators are the substances that cannot pass an electric current through them. Non-metals are bad conductors or insulators.
When an electric current passes through the human body, an electric shock is felt. It can results in skin burns, numbness, breathing problems, headache and muscle spasms. The severity of electric shock depends on the amount of electric current, time to which the body is subjected to current and the path of current through the body.
