Seatguru just doesn't know and one layout even says they "may" have limited recline just because there's a bulkhead behind them - a regular fudge from Seatguru. I think all of these three layouts (and the other layouts that Seatguru doesn't mention) have the same Economy seats but I've no personal experience of these specific ones. Hopefuly someone here has.
Whoever is in C will have someone's bum in their face a lot as people queue for the toilet.
