Solution

Official answer: A) Dynamic memory allocation
Runtime EnvironmentsDynamic memory allocation happens at execution time (runtime) when memory is allocated from the heap using functions like
malloc(),calloc(), ornew. It cannot be performed at compile time.Type checking is performed during the semantic analysis phase of compilation.
Symbol table management is handled throughout all phases of the compiler.
Inline expansion is a code optimization technique performed by the compiler.
Therefore, dynamic memory allocation is NOT performed during compilation. The correct option is (A).
