Explanation
The answer given is A (Algorithmic). However, estimating a story based on its relationship to one or more other stories is more accurately called Triangulating (option C), a form of relative estimation where a story's size is inferred by comparing it to already-estimated stories. Algorithmic estimation typically refers to formula-based approaches (e.g., COCOMO, function point analysis) that calculate estimates mathematically. Option C better matches the question's description - note this likely reflects an error in the answer key.
