A
Symbol table
B
Operator table
C
Literal table
D
Operand table
Explanation:

Detailed explanation-2: -Symbol Table is an important data structure created and maintained by the compiler in order to keep track of semantics of variables i.e. it stores information about the scope and binding information about names, information about instances of various entities such as variable and function names, classes, objects, etc.

Detailed explanation-3: -What are the data structures used for the implementation of the symbol table? Binary Search Tree, Hash Tables, and Linear search are the data structures used for the implementation of the symbol table.

Detailed explanation-4: -Symbol table is an important data structure used in a compiler. Symbol table is used to store the information about the occurrence of various entities such as objects, classes, variable name, interface, function name etc. it is used by both the analysis and synthesis phases.

Detailed explanation-5: -Symbol table is an important data structure created and maintained by compilers in order to store information about the occurrence of various entities such as variable names, function names, objects, classes, interfaces, etc.
