I'd just like to point out that no matter which answer you choose, you'll still be stuck with an OTN - that's 'Oh, too many numbers' for the rest of us!

B has got to be the right answer. An ODU is the building block of an OTN frame, so the tributary slot would definitely contain that.

Hmm, this is a tricky one. I'm going to go with D - an OH byte. The overhead bytes are a key part of the OTN frame structure, so that seems like the most likely answer.

I think it's C - an OPU. The OPU is the payload that gets encapsulated into the OTN frame, so it makes sense that the tributary slot would contain that.

I'm not sure, but I think it might be B) An ODU, as it also plays a role in OTN multiplexing.

I agree with Jamika, because OPU tributary slots are used for multiplexing OTN frames.
