Final answer:
The word 'enemy' is not an anagram of any country, unlike 'plane', 'chain', and 'serial'. 'Slow' was a potential typo as it does not form a country's name, though the rest do. Therefore, the correct option is d. enemy
Step-by-step explanation:
The word that is not an anagram of a country is enemy. An anagram is a word formed by rearranging the letters of another word. Using this definition, we can form the following countries from the other words:
- Plane is an anagram of Nepal.
- Chain is an anagram of China.
- Serial is an anagram of Israel.
- Slow is an anagram of Owls, however, 'Owls' is not a country, suggesting a potential typo or mistake in the options provided.
Thus, 'enemy' does not form the name of any country and is not an anagram of a country.
