Answer :
Final answer:
Exigent circumstances allowing for warrantless entry under Section 529.3(2) C.C are characterized by imminent danger, the necessity for immediate action, and no time for obtaining a warrant.
Explanation:
Section 529.3(2) of the Criminal Code allows for entry of a dwelling house under exigent circumstances. The conditions required for entry to be considered exigent are imminent danger, the necessity for immediate action, and the impracticality of obtaining a warrant due to time constraints. Therefore, the correct answer is 'b) Imminent danger, immediate action necessary, no time for a warrant'.
In legal terms, such circumstances are acknowledged when there's a pressing need to act and waiting to obtain a warrant could lead to harm to persons, destruction of evidence, or escape of a suspect. It is important to note that 'probable cause' remains a requirement for searches and seizures under normal circumstances, but when facing exigent circumstances, the urgency and necessity of the situation can justify warrantless entry.
