A is false.
the second operand is not always evaluated

that is called short circuit evaluation.
c is also false the expressions do not have to be boolean any numeric value is also allowed. It just to be zero or non zero
Answer:
Malware
Explanation:
It has the following characteristics:
• They are the most common in the network, and the difference with computer viruses is that they do not need user intervention.
• has the characteristic of replicating itself to expand through the networks to which a device is connected.
• When entering a computer, the worm tries to obtain the addresses of other computers through your contact lists, to infect them as well.
• They do not have to manipulate any program or make the computer malfunction, which makes them a little more difficult to detect.
• Take into account that Malware is "malicious software".
Routing is process of selecting and establishing the routes that data packets take on their way to a particular destination (specific IP addresses). Broadcasting on the other hand is the simultaneous transmission of the same message to multiple recipients. In contrast to routing, broadcasting lacks the ability to direct packets to a specific address. When it comes to security, routing is not necessarily more secure than broadcasting. Without goof security protocols other users can read messages even if they aren't the recipient of the packet.
