Answer:
Citrus and Bougainvillea contain thorns that originate from the auxiliary bud of a stem that provides protection.
Watermelon, cucumber, and pumpkin have modified auxiliary buds that form thin, wiry, leafless and spirally coiled branches and it helps the weak plant to climb the support known as stem tendrils.
Phylloclades are the modified stem present in Opuntia that helps in photosynthesis.
So, the correct option is 'Cucumber and Pumpkin'.
