Question: The language { 1 0 | n > = 0 } has context - free grammar with rules S - > 1 5

The language {1"0"| n >=0} has context-free grammar with rules S->150|0
Since the derivation S0 generates the string 0, which is not in the language, so the CFG cannot be correct.
Since the derivation S0 generates the string 0, which is in the language, so the CFG cannot be correct.
Since the derivation S0 generates the string 0, which is in the language, so the CFG is correct.
