HELP

Hello, can someone please explain the difference between answer choice D and answer choice E? I am failing to see how they are different no matter how many times I look over the wording. I probably missed something or diagrammed it incorrectly, so I would love for someone to double check my work. Thank you!

The stimulus lawgic I wrote is:

/D --> J

/J --> D

D --> Q

J --> Q

Q

The lawgic I diagrammed for (D) is as follows:

/L --> K

/K --> L

L --> M

K --> M

M

(E) Lawgic:

/D --> S

/S --> D

D --> C

S ---> C

C

Thanks!
