Where does smart contract reside?

1. The smart contract reside in the creator node. (If so, what if that particular node is lost then the smart contract is also lost?)
2. The smart contract reside in all the nodes in the network
3. The transaction which created smart contract alone resides in the ledger

The smart contract and the transaction are stored on every full node.

@astro So even if a node which created the smart contract fails, the smart contract will be there?

astro

Yes, once it is deployed to the network it is there forever unless the owner kills it.

From my understanding Ethereum contracts are as solid as stone.
