Answer:
d.All individuals involved in the lawsuit must have retained suitable legal counsel.
Step-by-step explanation:
For a lawsuit to be brought before a court of law, there should be a causal connection between the conduct in question and the injury, the party filing the lawsuit must have suffered harm or imminent harm and the likelihood that a favorable court decision will remedy the suffered injury among other reasons. All individuals must not necessarily have legal counsel, some may opt to defend themselves and some may seek legal counsel after the case have been brought before the court.
