Geometry

The answer is A. Through points H and K there is one line, line HK.

1. Recall the Two - Point Postulate:

The Two - Point Postulate states that through any two points, there is exactly one line.

2. Analyze each option:

A: “Through points H and K there is one line, line HK.”

Here, we have two points H and K, and it is stated that there is one line (line HK) passing through them. This directly demonstrates the Two - Point Postulate.

B: “Plane R and Plane Q intersect at line JM.”

This statement is about the intersection of two planes, which is related to the Plane - Intersection Postulate, not the Two - Point Postula...
