Which of the following is a penalty for importing merchandise contrary to law?

The correct answer involves significant penalties that reflect the severity of offenses related to the illegal importation of merchandise. In many jurisdictions, importing merchandise contrary to law can result in hefty fines and lengthy prison sentences, reflecting the seriousness with which such offenses are treated.

The outlined penalty of 20 years imprisonment or a $250,000 fine aligns with the established legal framework designed to discourage illegal import activities and protect domestic markets. High penalties are often imposed to deter potential offenders and reinforce the importance of adherence to trade laws and regulations.

The other choices present lesser penalties, which may not accurately reflect the legal consequences for serious importation violations. The absence of substantial imprisonment or fines in those options does not align with the gravity of illegal trade practices and their potential impact on the economy and public safety.
