Show answer & explanation
Correct answer: B
Answer: Either B or C must have occurred.
Explanation:
J occurs only if E or F occurs.
If E occurred, then C must have occurred (E occurs only if C occurs).
If F occurred, then B must have occurred (F occurs only if B occurs).
Therefore, if J occurs it follows that either B or C must have occurred.
Note: From B or C, D would also occur (since D occurs if B or C occurs), but the available choices focus on which of B or C must have occurred.
