[@Shahbazkhalid-oz7gs]

Hello Sir, You are one who change the way of learning, I was kind of rata type student but after learning from you I got better and better in every walk of life. You just changed my way of learning. Now I understand concept first and then solve questions which made me good at every subject. Sending love from pakistan. Thanks

@Fishing Freaks Shorts how will you get "G" then?

[@arghanath1092]

@@jatinsheoran1418 Is the question wrong? There is no way to get "G".

[@ArghyadeepPal]

HW2: No candidate key exists, there is no way to get G at all. Neither there is any attribute(or set of attributes) that can derive G, nor G(or set of combination of G with other attributes) can derive any given attribute.

[@shakuntalakamade]

hw2 answer is BEG , AEG , DEG
