The Correct Option isB
Solution and Explanation
Step 1 (Interpret the passage).
- Trust is defined as a subjective probability that someone will act in a way that benefits us.
- Thus, trust is not about certainty, but about confidence high enough to guide positive interaction. Step 2 (Test each option).
(A) Talks about testing whether someone will cheat us—this reflects suspicion, not trust.
(B) Cooperation arises when probability of beneficial behavior is high enough. This directly matches the passage: trust leads us to engage in cooperative action.
(C) Refers to "low enough probability of negative behavior"—framed incorrectly, since trust is about high probability of positive behavior.
(D) Avoiding defences relates to risk reduction, not the essence of trust as enabling cooperation.
(E) "Low enough for us to attack him" is opposite of trust—it reflects distrust. Step 3 (Conclude).
Only option (B) captures the essence: trust means we believe in someone’s beneficial action enough to initiate cooperation.
\text{Correct Answer: (B)} is high enough for us to consider engaging in some form of cooperation with him.
