Explanation
First, let's unscramble each word provided in the list:
LNUAIMMIU: This is ALUMINIUM (a metal/chemical element).
ELEST: This is STEEL (an alloy).
OPERPC: This is COPPER (a metal/chemical element).
NMKOYE: This is MONKEY (an animal).
INCKLE: This is NICKEL (a metal/chemical element).
Now, analyze the categories:
Aluminium, Steel, Copper, and Nickel are all classified as metals or metallic materials.
Monkey is classified as an animal.
Therefore, NMKOYE (Monkey) is the odd one out because it belongs to a biological category rather than the materials category.
Correct Option: (c) NMKOYE
