Which word best describes a person characterized as 'rapacious'?

The term 'rapacious' is specifically used to describe someone who possesses an insatiable appetite for wealth or material gain, often displaying excessive greed and a voracious nature that leads them to seize what they can, regardless of the impact on others. This aligns perfectly with the choice that defines a person as excessively greedy and grasping. The essence of 'rapacious' emphasizes a relentless and predatory approach to acquiring resources or power, making this the most fitting description among the provided options.

In contrast, the other options depict qualities that are fundamentally opposite to the nature of someone who is rapacious. Generosity, contentment, and altruism suggest a sense of giving, satisfaction, and helpfulness, which do not resonate with the characteristics implied by 'rapacious'. These terms reflect kindness and selflessness, highlighting the stark difference between a person driven by greed and one who prioritizes the well-being of others.
