Final answer:
The word 'WOW' does not have rotational symmetry.
Step-by-step explanation:
Rotational symmetry is the property that some objects have of looking the same after being rotated by a certain angle. To determine which word does not have rotational symmetry, we need to examine each word and see if it looks the same after being rotated. The word 'WOW' does not have rotational symmetry. When you rotate the word 'WOW' by any angle, it will not look the same.
