We can never be certain that the tree we infer is correct, as it is a model and not an exact representation of evolutionary relationships. However, we can test the statistical confidence of certain features of the tree using methods like bootstrapping or posterior probabilities. These tests give us an estimate of how well-supported the features of our tree are based on the data we have used. Therefore, choice B is the best answer.
