Explanation

The problem describes a symmetrical arrangement of points A and C around a central reference point B.
Point A is located 40m South-West of B, and Point C is located 40m South-East of B.
Because both points are at the same distance from B and have the same 'South' component in their direction, they must lie on the same horizontal (East-West) line.
A is on the western side of the central North-South axis, and C is on the eastern side.
Therefore, to travel from A to C, one must move directly in the East direction.

Option A: This is incorrect because both A and C are at the same southern latitude relative to B. Moving from A to C involves no southward movement.
Option B: This describes the direction of A as viewed from C. The question asks for the direction of C as viewed from A.
Option D: This is incorrect because it would require C to be both north and east of A. However, C is at the same southern level as A, not north of it.

Visual 1: Diagram: A compass rose with point B at the center. Vectors pointing from B to A (South-West) and from B to C (South-East), both of length 40m. A horizontal line connects A and C, with an arrow pointing from A to C labeled 'East'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Directional and spatial reasoning as background academic context rather than a clinical decision trigger.
This question tests logical and spatial reasoning, which are fundamental cognitive skills.
While not a clinical question, strong reasoning abilities are crucial for nurses in everyday practice for tasks like problem-solving, prioritizing care, and navigating complex hospital layouts.
These skills help in interpreting patient charts, understanding spatial relationships for procedures, and making quick, logical decisions under pressure.

How to Approach the Question

First, identify the central reference point, which is 'B' in this problem.
Next, sketch or visualize the positions of the other points (A and C) relative to the reference point. A simple North-East-South-West compass diagram is very helpful.
Pay close attention to the directional keywords: 'South-West' for A and 'South-East' for C. Notice that both share a 'South' component and are equidistant from B.
Analyze the relative positions of the two points in question (A and C). The symmetrical 'South' component means they are on the same horizontal line.
Finally, determine the direction from the starting point (A) to the ending point (C). Since A is to the west and C is to the east on the same line, the direction is East.
