Answer:
B. Spinning a spinner
Explanation:
A rigid transformation does not change the size or shape of the object ,that is why it is called a rigid motion. The object just moves, but remains the same.
So, as per definition, option B is the answer.
Enlarging a photo will increase its size. Filling a tire with air will also make the tire bigger. And slicing the log in sections will overall decrease the log size.
But only a spinner will remain the same in size, no matter how many times it is spins.
So, Option B is correct.
