The correct answer is D. Proof of guilt
When a finding is made that the facts alleged in a petition are true, it typically implies that the accusations or charges against someone are substantiated. In a legal context, this often leads to a determination of guilt, meaning that the individual is proven to have committed the acts they were accused of. Therefore, "proof of guilt" accurately describes the outcome of finding the alleged facts to be true. Choices A, B, and C do not accurately capture this concept and are therefore incorrect.
