B
Correct Answer
Determining whether an object's lifetime is bounded by the current function, enabling stack allocation and lock elision for non-escaping objects
Explanation
If the compiler proves obj never escapes a method (no external references), it can: allocate on stack (no GC), eliminate synchronization (no sharing). JVM HotSpot, GraalVM perform escape analysis for lock and allocation elision.
