Floral quartet complexes bind DNA through which domain?
Go with B — MADS domain. Under ABCE & ABCDE MODEL +Synapdrgon flowering, this is the standard explanation you’d use in class: it names the real driver or definition, while the rest are nearby but wrong. Not these: A) Homeodomain; C) bZIP domain; D) HLH domain. When two options sound similar, choose the one that matches the textbook definition most tightly.
