A developer uses VS Code for Solidity development and wants to see syntax highlighting, inline compiler errors, and the ability to deploy to a local Hardhat network without leaving the editor. Which plugin setup achieves this?

Install the Hardhat VS Code extension and the Solidity extension by Juan Blanco.

Install the Solidity Visual Developer extension and use the Foundry plugin for deployment.

Install only the Solidity extension by Juan Blanco and use the terminal to run Hardhat commands.

Install the Truffle VS Code extension and use the Remix IDE for compilation.

A developer is using Remix with MetaMask to deploy to a test network, but the transaction keeps failing with 'insufficient funds'. They have test ETH in their MetaMask wallet. What is the most likely cause and solution?

The contract has a bug that causes it to consume all gas; optimize the contract code.

The selected network in MetaMask is not the same as the one Remix is targeting; switch MetaMask to the correct test network.

Remix is using the JavaScript VM instead of Injected Provider; switch to JavaScript VM.

The ABI is incorrect; recompile the contract and try again.

In Remix IDE, which action is performed by the 'Compile' button in the Solidity compiler panel?

It converts Solidity source code into bytecode and ABI

It runs all unit tests in the project

It deploys the contract to the mainnet

It connects the IDE to a local blockchain node
