Solution
The correct option is B Pumpkin
The most common arrangement of the primary xylem and phloem is called a collateral bundle; the outer portion of the procambium (adjacent to the cortex) becomes phloem, and the inner portion (adjacent to the pith) becomes xylem. In a bicollateral bundle, the phloem is both outside and inside the xylem, as in Solanaceae (the potato family) and Cucurbitaceae (the cucumber family). Bicollateral vascular bundles are present in Cucurbitaceae family, examples Pumpkin, Ridge gourd. So, the correct answer is 'Pumpkin.'
