Probably they sent 1 BTC to someone and ~26 BTC (minus transaction fee) back to themselves (what is called a change output). The fee of a bitcoin transaction is given by sum of input values minus sum of output values

2 confirmations means the transaction was included in a valid block and that block was continued by another valid block.

Option 3, although it should be next block (older than the one that contains the transaction) instead of previous block.
