What's the benefit of using automatic properties in c#?

Question

See this two code:
https://code.sololearn.com/c3bYxiVRaUwu/?ref=app
https://code.sololearn.com/cA3qHE5oGZCN/?ref=app
On the first code I used variable in class and on the second code I used automatic properties in class. In this two code the answer is same.
So my question is what's the benefit of using automatic properties since we can do the same work using variable?
