Final answer:
The Parallel Postulate states that given a line and a point not on that line, there is exactly one line that passes through the point and is parallel to the given line.
Step-by-step explanation:
The Parallel Postulate is a statement in mathematics that relates to Euclidean geometry. It states that given a line and a point not on that line, there is exactly one line that passes through the point and is parallel to the given line.
This postulate is one of the five postulates that define Euclidean geometry and is used to prove many geometric theorems and properties. It is important in understanding the concept of parallel lines and their properties.
Therefore, the correct answer is: c. Exactly one.
