Concept:
In law, liability often depends on the presence or absence of intention and care:
• Mens rea → guilty mind (intention or knowledge)
• Actus reus → wrongful act itself
• Negligence → failure to exercise reasonable care
• Strict liability → liability without fault in certain cases
Step 1: Understand the given condition.
The act is done without intention or knowledge.
Step 2: Identify the legal concept.
When harm occurs due to lack of reasonable care (even without intent), it is termed negligence.
Step 3: Eliminate incorrect options.
• Mens rea → requires intention or knowledge
• Actus reus → refers only to the act, not the mental state
• Strict liability → applies in special cases regardless of fault
Step 4: Conclusion.
Thus, the correct answer is negligence.
