A NFT is a unique digital identifier that cannot be copied, substituted, or subdivided, that is recorded in a blockchain, and that is used to certify authenticity and ownership. NFT is the acronym for?

Non-fungible token

The correct answer is Option (2) - Non-fungible token (NFT)

Non-fungible means that something is unique and irreplaceable, unlike fungible items like money, where one dollar bill is equal to any other dollar bill. NFTs use blockchain technology to record ownership and ensure the authenticity of digital assets.
