  • Statement 1 is correct. The main objective of lexical analysis is breaking the program into a group of logical meaning words (Token).
  • Statement 2 is also correct here. The syntax analysis phase checks whether the token is syntactically correct or not. if yes then it produces the parse tree otherwise generates a syntax error.
  • Statement 3 is wrong here. Semantic means the meaning of language. syntax analysis phase only cares about the correct syntax of the program. programs are logically valid or not, this part is done by the semantic analysis phase.

$\textrm{Option (C) is correct.}$
