- B.⊕ ⚥ K(5) C(5) A5 G(2)✓
- C.% ⚥ K(5) C1+2+(2) A(9)+1 G1
- D.⊕ ⚥ P(3+3) A(3+3) G(3)
Correct Answer
(B) ⊕ ⚥ K(5) C(5) A5 G(2)
Solution & Explanation
The Solanaceae flower is actinomorphic and bisexual with five united sepals and five united petals, five epipetalous stamens, and a bicarpellary syncarpous superior ovary, giving the floral formula ⊕ K(5) C(5) A5 G(2). The option showing this actinomorphic, gamosepalous and gamopetalous (fused) pentamerous formula with epipetalous stamens is the correct one (option 2 = B). NCERT Reference: Ch 5, p.69, line(s) 5-10 — "Flower: bisexual, actinomorphic"
