Answer: Option (B) is the correct answer.
Explanation:
When an object moves from initial point A to final point B is known as displacement.
Thus, when a runner starts from initial point A and then after running for 1 mile it reaches to the same point A this means that displacement of the runner is zero.
Thus, we can conclude that out of the given options, the statement runner's displacement is zero is true.

The name given to an ion that has lost electrons is cation. Details about cations can be found below.
<h3>What is a cation?</h3>
A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.
Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.
A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.
Therefore, it can be said that the name given to an ion that has lost electrons is cation.
