Where is governance/approval for a new subnet submitted?

• A. On the C-Chain governance module.
• B. Through an external off-chain process with no chain integration.
• C. Direct governance by the subnet creator.
• D. On the P-Chain, where governance and approval occur.

Answer: (D)

Subnet governance is handled on the Platform Chain because the P-Chain is the part of Avalanche that manages network-level resources like validators, staking, and the creation and governance of subnets. Proposals to create a new subnet go through on-chain governance on the P-Chain, where validators participate in voting and approval. The C-Chain is just an execution layer for smart contracts and does not handle subnet governance. An external off-chain process or unilateral action by the subnet creator wouldn’t be enforced by the network. So, submission and approval occur on the P-Chain.
