Correct : b

Option B is the correct answer.
Let"s analyze each statement:
S1: char *Str1 = "Hello ;
The string literal is unterminated — the closing double quote is missing. The lexer cannot form a valid string token, making this a lexical error.
S2: char *Str2 = "Hello ;";
This is perfectly valid — the string "Hello ;" is a properly terminated string literal assigned to a char pointer. No error.
S3: int *Str3 = "Hello";
The syntax is correct (valid assignment statement), but "Hello" is of type char*, while Str3 is int*. Assigning a char pointer to an int pointer is a semantic (type) error.
Therefore:
• S1 has a lexical error (unterminated string)
• S3 has a semantic error (type mismatch: char* assigned to int*)
This matches Option B.
