the first one because if the president doesn't approve it then it's a vetoed bill, unsigned bill, or it dies and none of those are options- another answer crossed out was that it had to be introduced in the senate because unless it's a money bill it can be introduced in either house- the second one is false too because we don't get to decide if they are good laws or not- and lastly yes it must be approved by the entire congress which is the house and senate but that isn't the only thing that will make a bill a law
hope this helps
