Answer:
B) devious
Step-by-step explanation:
The word, 'unscrupulous,' as used in the sentence implies dishonesty or deviousness. The speaker in the passage draws a contrast between himself and a more dishonest person.
The more dishonest person uses unsound reasoning to back up his decision to engage in a morally unjust and questionable conduct. He decides to pass over a faulty coin to others, reasoning that nobody will be harmed by it. This understanding of the context helps us draw the conclusion that unscrupulous is synonymous with dishonest or devious.
