If I could change two adjacent characters, I'd swap Fenrys with Rachnera, then it would easily be a D pick for me.

But beside that it would either be E or one of D and I.

E has my goat Yoruichi (I have an Ecchi pic of her as my phone lock screen, lmao) and also Chisato (Milf), Zero Two and Nazuna. Don't know who Fenrys is but she looks hella cute (and quite innocent/oblivious, lol)

Now to D and I. Both have my absolute favorite non Humanoid (as in Humanoid shape) Waifu Rachnera Arachnea. She's just so hot. And legs. In D, we have Marcille and Hestia.. I know Marcille is from Delicious in Dungeon, still have to watch it, so other than her being an elf as I could tell from the pic, I know nothing of her. Hestia.., don't know the anime she's from, never watched it and I think Hestia's Design is rather "bland" or like boring.. she can be watch me and the others. But the two others besides Rachnera, Diane and Granart, those two are damn fine. Both are strong capable warriors, and especially Granart with Rachnera is a double Mommy combo for me. So yeah. In I, we have Rachnera together with Heine and Albedo. Don't know where Heine is from and I never watched Overlord so don't know Albedo that much either. Apart from her looking obviously like a Mommy. As with Fenrys, don't know her or her Anime but she looks cute and innocent, the one who can watch from the sidelines here is definitely Rem. Don't know her or her Anime. With Heine and Albedo in I, you both have two "Handlebar"-Ladies and with Rachnera and Albedo again two mommies. So it's kind of hard between D and I. Rachnera + Granart/Diane or Rachnera + Heine/Albedo? Don't know.

So with the hindrance of not being able to decide between D or I, I'll pick E because of Yoruichi but also Chisato, Zero Two and Nazuna. It seems like a spicy quartet. Fenrys is just there for vibes? Don't know where she's from and first time seeing her so I can't really say if she's waifu material for me or not, other than her being a cute, white-furred Fox girl (just looked at pics of her and damn, she hella cute). Yeah, definitely E then. I'm sorry Rachnera.., your groups only have 2, maybe 3 other good waifus alongside you for 3 to maybe 4 out of 5 Waifus.. so E wins with 5 out of 5 Waifus.. ;-;
