I need to know what version of Arduino UNO is this.
It is very urgent please someone help me.
All that I can say is that it does not appear to be a genuine Uno. When compared to my genuine Uno there are small differences.
Why the urgency?
Because the store is going to close and I need to buy the Arduino before my final exams, so I could work on it.
Are you sure it is not genuine, is there a way to check?
It does say made in Italy in the fourth image.
It will likely work for study.
Make certain store has a return policy.
No, I am not buying it for school, I am buying it for personal projects, but what I meant is that if the final exams start I am not going to have time to work on my projects.
I think I and other members are in a quandary; there is no way we can say for certain.
Yeah me too, I guess there is no way to find out 
Thank you for the help though.
I have 2 genuine Unos and 3 clone Unos from different vendors. They all work just fine and they all work the same.
At first, I wanted to know what version of Arduino UNO it is because the seller claims that it is Arduino UNO R3, but now I am even questioning if it is even original, but the seller says that he has distribution from Arduino.
The problem is that I bought 2 clone UNOs from different sellers and they both did not work.
I have even opened 2 discussions on this forum about them:
It's an Uno R3 or reasonably accurate clone thereof. It has the baseplate, it has the I2C pins, it has a 16u2 for the USB/Serial. It has a fancy box and Arduino trademark (which is illegal if it's not an actual Arduino product, but alas widely violated.) The silkscreen color doesn't look quite right, but that could be lighting or valid variation.
That's about all one can tell from the picture. It COULD be complete counterfeit board with fake chips that is totally non-working...
I bought it and I think it is original as it turns out that the place I am buying this Arduino from is actually distributor for Arduino
