which one is a scam test your self

a) so you were playing on a game and then someone told you hey can we be friends then you guys play for a lot of time together then he asks to get your number then you text each other every day then he tells you that he found a new game then sends you a link and begs you to play with him on the link to the game. b) a legitimate company account called you by your name correctly and asks you your card passcode and number
