I have been asked this question during an interview.

My question is based upon LR Parser in section Bottom Up Parsing of Compiler

Answer 1

Correct answer is (c) Consists of full or partial list of the tokens as they appear in the program created by Lexical analysis and used for syntax analysis and interpretation

Easy explanation: Each pass scans the program, the first pass generates the symbol table and the second pass generates the machine code.
