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.
Answer:

In option d there is also no multiply operator * in between 3.14 2 r it should be 3.14*2*r.
So we can say that option c is error free.
