How do Log-Structured Merge (LSM) trees maintain high write throughput compared to traditional B+ Trees in write-heavy environments?

A. By utilizing in-place updates on leaf nodes to avoid the overhead of allocating new disk blocks.

B. By keeping the entire index in memory and only flushing to disk during database shutdown events.

C. By buffering writes in memory and performing sequential disk I/O through a background compaction process.
