FT protein forms an active flowering complex with:

FD (C) is correct here. This is core VERNALIZATION & FLOWERING: once you know the definition or pathway step, FD is the clear fit. The wrong ones are A) LFY; B) SOC1; D) AP1. If the topic is about gradients or potentials, water/solutes move from higher to lower of the relevant quantity.

Epigenetic silencing of FLC involves:

That points to B: Histone methylation and chromatin remodeling. Compared with the other options, Histone methylation and chromatin remodeling is the one that correctly describes the VERNALIZATION & FLOWERING concept. The wrong ones are A) DNA mutation; C) Protein degradation; D) RNA splicing. If you’re stuck, eliminate anything that contradicts a basic fact you already know for this topic.

Most floral organ identity genes belong to which gene family?

Go with B — MADS-box. Under ABC MODEL, 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) Homeobox; C) bZIP; D) MYB. When two options sound similar, choose the one that matches the textbook definition most tightly.
