Answer:
![\boxed{=144--> C.}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D144--%3E%20C.%7D)
Step-by-step explanation:
<u><em>You had to used pemdas stands for: p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract that came from left to right.</em></u>
First you calculate with parenthesis first.
![(13-1)^2/2](https://tex.z-dn.net/?f=%2813-1%29%5E2%2F2)
![12^2/2](https://tex.z-dn.net/?f=12%5E2%2F2)
Then you calculate with exponents.
![12^2=12*12=144](https://tex.z-dn.net/?f=12%5E2%3D12%2A12%3D144)
![144/2](https://tex.z-dn.net/?f=144%2F2)
Next, divide from left to right.
![144/2=72](https://tex.z-dn.net/?f=144%2F2%3D72)
![144/72=2](https://tex.z-dn.net/?f=144%2F72%3D2)
![72*2=144](https://tex.z-dn.net/?f=72%2A2%3D144)
![2*72=144](https://tex.z-dn.net/?f=2%2A72%3D144)
![=72](https://tex.z-dn.net/?f=%3D72)
![2*72](https://tex.z-dn.net/?f=2%2A72)
Finally, multiply from left to right.
![72*2=144](https://tex.z-dn.net/?f=72%2A2%3D144)
![12*12=144](https://tex.z-dn.net/?f=12%2A12%3D144)
Final answer: ![\boxed{=144}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D144%7D)
