Explanation

MSIR (a graph-based function Intermediate Representation) is designed around functional semantics, so it natively supports concepts that define how functions relate to data and other functions. Free variables (A) are a core functional concept - captured values from outer scopes - that graph edges explicitly model as dependencies. Higher-order functions (B) - functions that accept or return other functions - are first-class in functional IRs and map naturally onto function nodes with function-typed edges. Recursion (D) is representable as a cycle or self-referential node in the graph structure, which graph-based IRs handle well.

Interrupt (C) is wrong because it is a hardware/OS-level imperative control-flow mechanism, not a functional semantic construct - it falls outside the functional programming model that MSIR is built around.

Memory tip: Think "FHR" - Free variables, Higher-order functions, Recursion are the three pillars of functional semantics. Anything tied to the hardware layer (like interrupts) belongs to imperative/systems programming, not a functional IR.
