Classify the following curves as (i) Open or (ii) Closed.

Explanation

To classify the given curves as open or closed, we need to understand the definitions of open and closed curves:

1. **Open Curve**: An open curve is one where the starting point and the ending point do not coincide. In other words, if you trace the curve from the starting point to the ending point, you will not return to the starting point.

2. **Closed Curve**: A closed curve is one where the starting point and the ending point coincide. This means that if you trace the curve, you will return to the starting point.

Now, let's classify the curves step by step:
