Final answer:
Black box testing is the odd one out as it involves testing without knowledge of the internal structure, in contrast to white/glass/clear/transparent/structure box testing which all entail knowledge of what is inside the box.
Step-by-step explanation:
The odd one out among the options provided is D. Black box testing. Options A, B, C, E, and F are all synonyms that describe a software testing methodology where the internal structure/design/implementation of the item being tested is known to the tester. This is also known as white-box testing or structural testing. The terms "white box", "glass box", "clear box", "transparent box", and "structure box" all imply some level of transparency into the structure of the software. On the other hand, black box testing is a method where the internal structure is not known and testing is based on the specification and functionality.
