D.

Deterministic Wallets

Suggested answer: B

Explanation:

Brain Wallets derive private keys from a passphrase. This approach allows users to create a wallet by memorizing a unique phrase, which is then hashed to generate the corresponding private key.

Key Details:

Use of Passphrases: Brain wallets use a passphrase that is entered by the user, typically a string of words that can be remembered easily. This passphrase is then converted into a private key using a cryptographic hash function.

Security Concerns: While convenient, brain wallets are susceptible to brute-force attacks if the passphrase is not sufficiently complex. Simple or common phrases may be vulnerable to attackers who use lists of common phrases to derive potential private keys.

Distinction from Deterministic Wallets: Unlike Hierarchical Deterministic Wallets, which use a seed phrase to generate a tree of keys, brain wallets derive a single private key directly from a passphrase.

In conclusion, B. Brain Wallets is the correct answer, as these wallets use a passphrase to generate the private key.
