1. A Substrate client contains _ . Check all that apply.

• A. A storage component.
• B. A runtime.
• C. A peer-to-peer network component.
• D. A consensus layer.

2. A Substrate runtime contains _. Check all that apply.

• A. All state transition functions of a Substrate blockchain, often in the form of “pallets”.
• B. An executor, which dispatches calls to the runtime.
• C. The ability to compile to WASM.

3. Substrate is _. Check all that apply.

• A. A blockchain.
• B. Built with Rust.
• C. Can only be used with Rust.
