B. Provides a way to influence the court when expert testimony is not allowed
Step-by-step explanation:
Amicus Curiae briefs are filed by the people who have interest in the subject matter of the lawsuit but they are not party to the litigation. Amicus curae means "friend of the court" briefs. It helps to provide sympathetic advocate to address policy issues and expand the effects of a potentially important prior court opinion
Filing of amicus brief signals the court that the case is important and related to many issues apart form the litigants interests. e.g An amicus curae about public health speaks a lot about the health significance of the policies at stake.
