Choose the correct answer below.

A.

angle∠COBCOB

and

angle∠BOCBOC

B.

angle∠OCBOCB

and

angle∠OBCOBC

C.

angle∠CBOCBO

and

angle∠BCO

To identify other ways to name an angle with vertex at a point, it's essential to look at the three points forming the angle and focus on the vertex. Here, if we have an angle denoted as ∠Z, it implies Z is the vertex of the angle. Let's examine each option:

- **Option A: \( \angle COB \) and \( \angle BOC \)**  
- **Option B: \( \angle OCB \) and \( \angle OBC \)**  
- **Option C: \( \angle CBO \) and \( \angle BCO \)**

The correct answer is:

**A. \( \angle COB \) and \( \angle BOC \)**

### Explanation:
An angle can be named by listing its points in order, with the vertex in the center. For angle \( \angle Z \) with points \( C \), \( O \), and \( B \) (where \( O \) is the vertex), \( \angle COB \) and \( \angle BOC \) are correct ways to name it.
