Answer: D. Partially true. Depends on the specific countries involved, both of the virus author and the recipient.
Step-by-step explanation:
Virus writing is not illegal if you keep it on your computer. But infecting other computers by releasing them across the internet without the owners' permission is completely unacceptable, and unauthorized access and it is a crime in many countries like the U.S. and most jurisdictions around the world.
But some countries are slow or ignorant to introduce cybercrime laws. for example Case against Onel de Guzman(creator of the virus) in Phillippines who were responsible for creating LoveBug virus, was released by the government because there were no laws to handle this kind of crime at the time of his arrest.
Hence, the correct option is D. Partially true. Depends on the specific countries involved, both of the virus author and the recipient.
