Explanation
Story points estimate effort using relative sizing-comparing stories to each other rather than assigning absolute time values. A story worth 8 points is roughly twice as complex or effortful as one worth 4 points, but no specific hours are implied. Ideal time (option A) is an absolute measure (e.g., 'how long if there were no interruptions'). Bottom-up (option B) is a cost-estimation approach that sums detailed task estimates. Little's Law (option D) is a queuing-theory formula relating throughput, cycle time, and work-in-progress-not an estimation technique.
