Answer: (d) None.

Explanation: None of the trees mentioned, namely Jackfruit (Artocarpus heterophyllus), Mahua (Madhuca indica), and Teak (Tectona grandis), are deciduous trees.

Deciduous trees are those that shed their leaves seasonally, typically during the autumn or dry season. On the other hand, these three trees mentioned in the question—Jackfruit, Mahua, and Teak—retain their leaves throughout the year and are classified as evergreen trees.
