In criminal cases, the state is required to share with the defense any information or evidence that could assist the accused. this evidence is called:

Exculpatory evidence

Explanation:

Exculpatory evidence is "any evidence in a criminal trial that supports the idea that the defendant is not guilty".

So for this case is the best option since we want the information or evidence that could assist(or help) the accused.

This is an evidence favorable to the defendant in any trial and can exonerates or help in order to exonerate the defendant.

Other important thing is that is the opposite of inculpatory evidence, which try to present guilt the accused.
