Step-by-step explanation:
Arc length = radius * central angle (measured in radians)
There are

C. I, II, and III
I’m sure it’s the answer not positive though, I’m sorry.
The first reaction represented is a decomposition reaction due to the fact the bonded pair are being split apart.
The second equation is a single displacement because the B and C have switched places, which is the only change making it a single displacement. If there had been another bond and A had also moved, it would be double.
Answer:
C will be the rightful answer
