Which of the following is NOT a data structure commonly associated with assemblers?

Assemblers typically use data structures such as Symbol Tables (for storing symbols and their values), Literal Tables (for storing literal values), and Opcode Tables (for mapping mnemonics to machine instructions). However, a “Directive Table” is not a standard data structure in the context of assemblers. Directives in assembly language are instructions to the assembler itself, not the data structures it uses during the assembly process.
