What is a Polymorphic Virus?

What is logic bomb?
A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files (such as a salary database trigger), should they ever be terminated from the company.
Software that is inherently malicious, such as viruses and worms, often contain logic bombs that execute a certain payload at a pre-defined time or when some other condition is met. This technique can be used by a virus or worm to gain momentum and spread before being noticed. Some viruses attack their host systems on specific dates, such as Friday the 13th or April Fools’ Day. Trojans that activate on certain dates are often called “time bombs”.
To be considered a logic bomb, the payload should be unwanted and unknown to the user of the software. As an example, trial programs with code that disables certain functionality after a set time are not normally regarded as logic bombs.
I would pick B.

Sorry, I have to agree with polymorphic virus. I think “changes…to avoid detection” is the crucial part. “Specific dates at specific times” was added to confuse the question a little.

I agree with Dugan.
The KEY in here is that the “Malware that changes its binary pattern”
Logic bombs, whilst triggered at a certain time, DO NOT change their “binary Pattern”
The “Specific dates at specific times” is indeed a red-herring which was added to confuse the question a little.
