the answer of the book is (B,D,E)
Why C is not right answer ?

C is not a correct answer since a crossover cable is needed to connect a hub and a switch and not a straight-through cable.

Like devices use cross over cables. If you look up switches and hubs you will find they use the same send and receive pairs.
The question asks about the cable but to understand why you choose the cable you need to understand which pins the device uses for sending and receiving data. -

Hubs and Switches are like devices. Think of it this way --
A PC plugs into a Switch which plugs into a Router
A PC plugs into a Hub which plugs into a Router
A WAP plugs into a Switch which plugs into a Router
These connections use Straight-Through. Skip a link and you need a Crossover. Same goes for two of the same device (crossover) -- Router to Router, Switch to Switch, Hub to Hub.R&S: CCENT → CCNA → CCNP → CCIE [ ]
