Explanation:

- The statement “What judges do, and what they profess to do, are not always the same, and the latter is only evidence of the former-often very misleading evidence” points to the idea that the actual behavior of judges may differ from what they claim to follow, suggesting that judicial decisions are influenced by more than just stated legal rules.

- Option 1: Austin – John Austin was a legal positivist, but he mainly focused on law as commands, not this specific judicial insight.

- Option 2: Allen – C.K. Allen wrote about law and interpretation but is not credited with this observation.

- Option 3: Jethro Brown – Jethro Brown was a legal theorist focusing on law’s purpose and function, but did not make this exact remark.

- Option 4: Buckland – W.W. Buckland was known for Roman law studies, not for this statement.

- The correct answer is Option 2: Allen (C.K. Allen).

Correct Answer: Option 2 – Allen
