By saying that no human being will be justified in the sight of God by works, Paul meant that

A.

The mosaic law was useless in ensuring justification for man

B.

The law had been weakened in human flesh

C.

Knowledge of sin came through the law

D.

Moses who gave the law was not justified by the law

Correct answer is C

Paul's teachings emhasise that justification before God is not achieved through works or adherence to the Mosaic law. Instead, the law reveals the knowledge of sin and highlights humanity's need for redemption and salvation through faith in Christ.
