The diagram shows three UPS modules, each 100 kW, connected in parallel to support a 100 kW IT load. That means:
One module (100 kW) can support the load (N).
Two additional modules are installed as redundancy.
This equals N+2 redundancy.
2+N+1 and 2(N+1) imply dual active paths not shown.
N+N+N is not an industry term.
Thus, the correct redundancy level is N+2.

I feel like I’ve seen N+N+N in a different context, but I’m not confident it applies here.

I'm leaning towards D) 2(N+1) because it sounds familiar, but I need to double-check my notes on redundancy setups.

I remember practicing a question similar to this, and I think N+2 was a common answer, but I can't recall the specifics.

I think the redundancy setup might be 2+N+1, but I'm not entirely sure how to differentiate it from the others.
