A triangle with three (3) sides is most likely the next step in the series: option C.
Inductive reasoning can be defined as a process that involves drawing and arriving at a general conclusion (conjecture), especially by observing a pattern that is based on a sequence (series) or specific instances.
Based on the geometric shapes shown in the image attached below, we can deduce the following patterns and rules:
Rule: The sides of the geometric shapes are decreasing by one (descending order).
Therefore, we can infer and logically deduce that the next shape in the series must have three (3) sides, which is a triangle.
