Strong 128-bit encryption.

Explanation: An individual character corresponds to 8 bits . So if there are 16 characters then,

168=128 bits keys

This makes the 128 bit key encryption the strongest amongst all other options.It is strongest because it is almost impossible to decode the 128-character key  by any method e.g.-brute-force method.

Other options are incorrect because the characters given by the other bits are as follows:  =32 characters

                         =64 characters

                         =128 characters  

Thus, the strongest character key is of 128 bits. for cipher.

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
