Which shape has no straight lines?
Correct answer: B. Circle
- A. Triangle
- B. Circle
- C. Rectangle

Explanation
The correct answer is the circle. A circle is unique among these options as it has no straight lines; it is perfectly round and every point on its edge is equidistant from its center. In contrast, a triangle, rectangle, and pentagon are all polygons, each with a set number of straight edges and vertices.

About Logical Problems
Logical problems present several conditions about people, objects, events or choices and require their possible arrangements to be tested. They cover constraint-based reasoning, rankings, matching, grouping, scheduling and elimination, with attention to the difference between a complete solution and a possibility that merely satisfies one condition.
