In ABC model, class B genes specify:

B fits best: Petal and stamen identity. Keep the PSS-Sec-E-Sensory biology basics straight and Petal and stamen identity stands out as the precise answer. Avoid: A) Sepal identity; C) Carpel identity; D) Ovule identity. Light and flowering items often hinge on which photoreceptor or day-length rule is in play.

Class A genes in ABC model include:

Go with A — AP1 and AP2. Under PSS-Sec-E-Sensory biology, 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: B) AP3 and PI; C) AG alone; D) SEP genes. When two options sound similar, choose the one that matches the textbook definition most tightly.
