A flower is zygomorphic when it can be divided into two equal halves in only one vertical plane. NCERT names pea, gulmohur, bean and Cassia as zygomorphic, while mustard, datura and chilli are actinomorphic. Hence only Gulmohar (b) and Cassia (c) are zygomorphic, giving option B. NCERT Reference: Ch 5, p.62, lines 21-23 — "it is zygomorphic, e.g., pea, gulmohur, bean, Cassia"
