Directions :
A causes B or C, but not both,
F occurs only if B occurs,
D occurs if B or C occurs,
E occurs only if C occurs,
J occurs only if E or F occurs,
D causes G, H or both,
H occurs if E occurs,
G occurs if F occurs.
If J occurs, which must have occur?
If \(J\) occurs then either \(E\) or \(F\) occurs and if \(E\) occurs then \(C\) must occurs, if \(F\) occur then \(B\) must occur so we can say if \(J\) occurs either \(B\) or \(C\) will occur.\[\]Choice (B)\[\]
