Cisco question - why others options are wrong?

[oldcavalheiro]

Why letter A and D are wrong answers in this Cisco question???
to me "3G ,4G" and "mobile phone service provider" also provide internet connection

A student purchased a new Wi-Fi-enabled tablet computer. What is required to connect this device to the internet?
A - a 3G or 4G network
B - a telephone company
C - a wireless LAN
D - a mobile phone service provider
explain: To access the internet using WiFi the tablet will need to access a wireless LAN.

It says only Wifi enabled devices so only Wireless is the Option here.

Wireless is the mostly accurate option here, but 3G or 4G also connect Wi-Fi-enabled devices to the internet through service provider.
But i see now how Cisco Questions works, then could put (choose two or three), but then choose only one and the right answer become the best choice that in this case is wireless. Cisco had many Trick questions

if you multiply then 3G/4G is also an answer.
