- B . Configuring the Peer-to-peer endorsement options.

- B . Both chaincode and block events
- C . Neither chaincode nor block events
- D . Only chaincode events

- A . Order and package endorsed transactions into a block.
- B . Order new tokens from the token issuer.
- C . Order peers to endorse a transaction.

- A . UNAVAILABLE
- B . ABORTED
- C . DEADLINE EXCEEDED
