Answer:c. probable cause
Step-by-step explanation:
What is a probable cause ?
A probable cause is used to refer to what the police need to have as a tangible cause or reason before they can make an arrest or receive a search warrant.
This means that a courts must find tangible reasons or sufficient evidence that indeed there has been a crime that has occured for them to actual arrest that person or for them to require a search to be done in that particular place .
However under an urgent situation a probable cause can be enough reason for the law authorities to search the area without a search warrant, for example when there is a reason to believe that someone's life is in grave danger.
If someone is arrested under these circumstances (without a warrant present) he will quickly be brought infront of the judge who will have to determine a probable cause.
