66,73 73-66=7
13,21 21-13=8
10,20 20-10=10
the missing no. is 9 so
52+9=61.
the pattern is
66,73,13,21,52,61,10,20

Answer:
Option (b) When the end-user device will run an application that requires a dedicated connection to the network 
Explanation:
- Option (b) is the correct option. 
- When the user device requires a highly dedicated network environment to itself to run a web application that requires large download and upload speeds, bandwidth requirements then it prefers a wired connection than a wireless connection.
- If the wireless signal is within the reach, then it advisable to go for a wireless connection than a wired connection. A wired connection requires other hardware equipments like a internet connection cable etc. which is not required in case of wireless connection. So, option (a) is wrong option.
- WLAN NIC is a wireless interface network controller that connects to a wireless radio based network than a wired network.So, option (c) is wrong option. 
- Delay torrent network is designed to operate where continuous network connectivity is not available like extreme terrestrial spaces, space communications, inter planetary communications etc.So, option (d) is wrong option.
