Every aspect of this question is either wrong, poor decision making, incomplete data, or from the year 2000 or earlier. If this switch is connecting to another switch (doesn't say) it needs a cross through cable. A and B are out cause never mentioned coaxial, Fiber being used. C is out for 2 reasons again assuming its a switch to switch connection. 1 straight through cable and 2 WHO IS USING CAT5!!!! D is a cross through cable back in the year 2000 as half the line wasn't being used anyway so no reason to swap pins 45 and 78. So this would be a bad decision unless you are using a 10/100 switch as that would be the speed you are going at. If you see this question on your test the network + certification is useless or this is a fake test as again this was only true in 19XX.

No people it's not same Straight-through or crossover for same or opposite device. The question states no "auto-MDIX" feature is one that allows Straight-through to able to work on switches. If such feature is not available then u have to use crossover cable. Rollover is for console use. By my understanding.

I’m an idiot, it’s the other way around, so the answer given is correct.

When connecting same devices we use straight-through cable, when we have two different devices is cross-over. I don’t get why the answer is crossover (I’m confused).

That is not correct. When connecting like devices you use a cross-over cable: switch to switch, router to router, hub to hub. There is an exception here and that is connecting a router directly to a host. When connecting unlike devices you use a straight-thru cable: switch to a host, hub or router to a switch.

But isn't a straight through cable suppose to be used with a PC and a switch?

"switch that needs to be connected to the existing switch" so crossover.

The answer reads as though two connectors are on each end.

Is a cable with TIA/EIA 568a and 568b on each end proper crossover cable??? Professor Messer says this is not the proper type of crossover cable and will not work!? The pins 1-3 and 2-6 has to be changed.
