Question

Choose the incorrect pair (and = all, only = only).

\[ \begin{array}{|c|l|l|l|} \hline & \text{Type of fruit} & \text{Example} & \text{Character} \\ \hline \text{A} & \text{Pepo} & \text{Cucumber} & \text{Develops from inferior ovary} \\ \hline \text{B} & \text{Legume} & \textit{Pisum} & \text{Dehisce ventrally} \\ \hline \text{C} & \text{Caryopsis} & \textit{Oryza} & \text{Pericarp and seed coat are unfused} \\ \hline \text{D} & \text{Sorosis} & \text{Pineapple} & \text{Inflorescence develops into fruit} \\ \hline \end{array} \]

• A. A and B only
• B. A and C only
• C. C and D only
• D. B and C only

Hint:

Remember: \[ \boxed{ \begin{aligned} &\text{Pepo} &&\rightarrow \text{Inferior ovary} &\text{Legume} &&\rightarrow \text{Dehisces along both sutures} &\text{Caryopsis} &&\rightarrow \text{Pericarp fused with seed coat} &\text{Sorosis} &&\rightarrow \text{Multiple fruit} \end{aligned} } \]

Answer 1

The Correct Option is D

Step 1: Examine each pair. Statement A is correct. Pepo develops from an inferior ovary. Statement B is incorrect. A legume fruit dehisces along \[ \boxed{\text{both dorsal and ventral sutures}.} \] Hence, "dehisce ventrally" alone is incorrect. Statement C is incorrect. In a caryopsis, \[ \boxed{\text{pericarp and seed coat are fused}.} \] Therefore, the given statement is incorrect. Statement D is correct. Sorosis is a multiple fruit formed from an entire inflorescence, e.g., pineapple.

Step 2: Choose the incorrect pairs. Hence, the incorrect pairs are \[ \boxed{\text{B and C only}.} \] Therefore, the correct option is \[ \boxed{(D).} \]
