The Correct Option is B
Solution and Explanation
Concept:
Ovules are classified on the basis of their orientation with respect to the funicle, micropyle and chalaza.
Among all types of ovules, anatropous ovules are the most common in angiosperms.
Step 1: Recall the structure of Pisum. Pisum (pea) belongs to family Fabaceae. Members of Fabaceae typically possess anatropous ovules.
Step 2: Understand anatropous ovule. In an anatropous ovule:
• The ovule becomes inverted during development.
• The micropyle lies close to the hilum.
• The body of ovule turns through approximately \(180^\circ\). This arrangement is the most widespread among flowering plants.
Step 3: Compare with other ovule types. Orthotropous ovules remain straight. Campylotropous ovules are curved. Hemianatropous ovules are partially inverted. None of these are characteristic of Pisum.
Step 4: Final conclusion. Therefore the ovule present in Pisum is: \[ \text{Anatropous ovule} \] Hence option (B) is correct.
