Subject :NSO    Class : Class 2

Ans 1: (Master Answer)

Admin from revisewise, Noida
Class : Class 1

C

In option A tomato is the odd member as seeds of kidney beans and pea are edible whereas fruit of tomato is edible. In option B fruits of brinjal and pumpkin are edible whereas root of turnip is edible, so it is the odd member. Similarly in option D radish is the odd member as here root is the edible part whereas in potato and ginger modified stems are edible. In option C, sugarcane is the odd member as its stem gives sweet juice whereas in cabbage and lettuce, leaves are edible. Hence, in option C the odd member is incorrectly encircled.
