Specifically, it helps in determining if the harm would have occurred "but for" the defendant's actions. If it can be shown that the claimant's injury would not have occurred without the defendant’s conduct, then a causal link is established.

In this scenario, answer C directly reflects the function of the "But For" test, as it focuses on establishing that the claimant's harm is directly linked to the defendant’s actions, rather than occurring independently. This test is essential in legal contexts where proving causation is necessary for the claimant to succeed in their case, as it is crucial to demonstrate that the actions of the defendant were a necessary factor in the harm experienced by the claimant.
