From the setup, we can think about who each character can pass to:
J can pass to K/L
K can pass to L/M
L can pass to K/M
M can pass to anyone, but since no one else can pass to J, M has to always pass to J.
As we consider each answer choice, we need to think about Who's Left and decide whether they're eligible passing to each other.
(A)
J -> K
K -> M
Those are legal. Who's left?
L ->
M ->
we know that M passes to J always, so that forces L to pass to L. Eliminate.
(B)
J -> L
L -> M
Those are legal. Who's left?
K ->
M ->
M passes to J, so that leaves K to pass to K. Eliminate.
(C)
J -> M is illegal, so get this outta here.
(D)
K -> L
L -> K
That leaves
J ->
M ->
M has to pass to J, so J has to pass to M, which is illegal. Eliminate
(E)
K -> L
L -> M
this leaves
J ->
M ->
M has to pass to J, and that leaves J passing to K, which is fine. This is the correct answer.
