Survey :) College Girls

Hello I have am taking a psych survey for class. If you are a GIRL between the ages 18 - 25 please participate in my survey. Please :D 
​On a scale from 0-10 (0= bad, 10= good) how successful would these methods be for a cute stranger to get your number and get to know you? If hypothetically you were single and were interested in dating men. 
​A. Nice shy guy has the confidence to approach you and say "hello, I'm sorry to put you on the spot, but I think you are very pretty, would you be willing to give me your number?" 
​B. Guy asks you for a recommendation for a nice nearby resteraunt, after you guys have a great conversation he asks if he can take you there for lunch someday to continue the nice conversation. 
​C. Guy sits at your table at Starbucks, starts conversation with you, then asks for your number. 
​D. Guys sits at your table at Starbucks, starts a conversation, then asks if he could buy you coffee sometime. 
​E. Guy sees your picture on tinder and says you're hot. 
​F. Guy approaches you in the grocery store and asks you what your favorite dish is. Then buys the ingredients and asks if he can cook it for you sometime. 
​Thank you for helping me with this survey. With this information I will show guys that it pays to be confident, but polite, and certainly not crude. So many guys ask me what an appropriate way to approach a stranger he finds attractive is, but I honestly don't have the answer. Every woman is different. If you have an idea for something that might work better please let me know. But first rate very single one of my options! Thanks! 
​Also please add your age! :) ??
