The answer is: D
Explanation
The correct option is D: Extortion.
According to Section 383 of the Indian Penal Code, extortion is defined as "Whoever intentionally puts any person in fear of any injury to that person, or to any other, and thereby dishonestly induces the person so put in fear to deliver to any person any property or valuable security, or anything signed or sealed which may be converted into a valuable security, commits “extortion”."
In this case, 'A' intentionally put 'B' in fear of death, which is an injury to 'B', and thereby dishonestly induced 'B' to deliver a sum of Rs. 10,000/-, which is a property, to 'A'. Therefore, 'A' committed extortion.
Cheating is different from extortion, as cheating involves deceiving a person and inducing them to deliver any property or do or omit to do anything, whereas extortion involves putting a person in fear of any injury and inducing them to deliver any property or valuable security.
Robbery is also different from extortion, as robbery involves theft or extortion by using force or causing fear of instant death, hurt or wrongful restraint, whereas extortion involves putting a person in fear of any injury and inducing them to deliver any property or valuable security.
Mischief is also different from extortion, as mischief involves causing damage or loss to any property, whereas extortion involves putting a person in fear of any injury and inducing them to deliver any property or valuable security.
