I don't know what is available or pricing where you live. But these would be inexpensive parts in the US.
The first one would be a budget Intel build. The second one would be a budget AMD build. For the long term, you would probably be better off with the AMD build as the AM4 socket will be supported for several more years and the Intel socket is going away. But, the Intel setup is $50 less. I don't know what that translates in INR.
If the AMD build is over your budget, then go with the Intel build and do not get the A320 board.
