Correct answer & explanation
✓
Heap memory area
The correct components of the JVM listed here are: Heap memory area (C), Execution engine (D), and Class loader subsystem (E). The Java compiler (B) is part of the JDK, not the JVM. Java source code (A) is input to the compiler, not a JVM component. The class loader loads bytecode into the JVM, the heap stores objects, and the execution engine executes bytecode.
