Which one of the following set of trees does not belong to Temperate Floral Zone of Himalaya?

The temperate floral zone of the Himalayas, typically ranging from 1500 m to 3500 m, is characterized by species such as Oak, Maple, Rhododendron, Birch, Laurel, and Walnut [3]. Specifically, Himalayan moist and dry temperate forests feature broad-leaved oak, maple (chinar), and various rhododendrons [2]. Birch and laurels are also prominent in the temperate and sub-alpine transition zones [4]. While Magnolia is found in the temperate forests of the Eastern Himalayas, Cashewnut is a tropical species primarily grown in coastal regions and lower altitudes of Peninsular India, not in the temperate Himalayan zone. Therefore, the set containing Cashewnut does not belong to the temperate floral zone. Other listed trees like Oak, Maple, Rhododendrons, Birch, and Laurels are well-documented components of the Himalayan temperate vegetation [3].
