Correct answer: D. One standardised way to connect, so that anything implementing it can be plugged into anything else.
Explanation
The principle — An analogy is a claim about one property, and reading a second property into it produces a confident wrong answer.
Why the key is correct — The documentation asks you to think of MCP like a USB-C port for AI applications, and then says which property it means: just as USB-C provides a standardized way to connect electronic devices, MCP provides a standardized way to connect AI applications to external systems. The shared property is the connector, not the cable.
Why the others are wrong — Throughput, capability parity and physical transmission are all things USB-C happens to have, and none of them is the thing being compared.
Remember this — The port is standard; what is plugged into it is not.
Sources — MCP first-party documentation.
