Answer: 
   Connection-oriented is the method which is implemented in the transport and data link layer. It is basically depend upon the physical connection in the network system. 
Transmission control protocol (TCP) is the connection oriented and user datagram protocol (UDP) is the connection less network transport layer. The TCP and UDP both are operate in the internet protocol (IP).
 It basically require connection and it can be establish before sending data. This is also known as reliable network connection service. The connection oriented service establish connection between the different connection terminal before sending any data or information. It can easily handle traffic efficiently. 
 
        
             
        
        
        
Answer:
Option c.
Explanation:
AM refers to the amplitude modulation.
AM refers to the modulation of a wave used as a means of broadcasting an audio signal by combining it with a radio carrier wave and varying its amplitude
An increase in message amplitude, Am, results in a higher AM Index.
An AM index between 0 and 1 indicates the received modulated signal will have minimal distortion.
So, option c. is correct.
