Answer:
B. extortion.
Step-by-step explanation:
In the context of law, extortion is defined as a criminal offence where an offender/criminal obtains something, particularly money or property, through force or violent threats.
If we look into the above scenario, the two criminals have committed a series of offences, however, they did not force nor threat the client to invest his money into their scheme. Therefore, they cannot be charged with extortion by the court.
Instead they would be charged with criminal conspiracy for scheming a fraud, money laundering for transfering the money into their family business to conceal income and deceit for deceiving the man with lies.
