Consider four possible key distributions for a sorted key-to-position mapping in a disk-based index: (A) Stable and approximately linear over time (B) Stable but highly non-linear with sharp local irregularities (C) Unstable but approximately linear: the distribution shifts over time but maintains an almost linear shape (D) Unstable and highly non-linear: the distribution changes frequently and has sharp irregularitiesNow assume we use a traditional disk-resident B+Tree that stores keys in sorted order and navigates via key comparisons.Which statement best describes how these settings affect B+Tree lookup performance?
