C. `[Cu{O=C(NH_(2))_(2)}]Cl_(2)`
D. `[CuCl_(2){O=C(NH_(2))_(2)H_(2)}]`

Explanation

To determine the formula of dichlorobis(urea) copper(II), we will break down the components of the name step by step.

### Step 1: Identify the Components
The name "dichlorobis(urea) copper(II)" can be broken down into:
- "dichloro" indicates there are two chloride ions (Cl).
- "bis(urea)" indicates there are two urea ligands.
- "copper(II)" indicates that copper is in the +2 oxidation state.

### Step 2: Write the Ligand Formula
Urea is represented by the formula NH₂C(=O)NH₂. Since we have two urea ligands, we will denote this as:
- 2 urea = 2(NH₂C(=O)NH₂)

### Step 3: Write the Chloride Ions
Since "dichloro" indicates there are two chloride ions, we write:
- 2 Cl⁻

### Step 4: Combine the Components
Now, we combine the components to form the complete coordination compound. The central metal ion is copper (Cu) with a +2 oxidation state. The overall formula will be structured as follows:
- Cu(II) will be the central atom.
- The two chloride ions will be written first (C for Cl).
- The two urea ligands will follow.

Thus, the formula can be assembled as:
- CuCl₂(NH₂C(=O)NH₂)₂

### Step 5: Finalize the Formula
To simplify, we can condense the urea part:
- The final formula can be written as: [CuCl₂(NH₂C(=O)NH₂)₂]

### Conclusion
The formula of dichlorobis(urea) copper(II) is:
**CuCl₂(NH₂C(=O)NH₂)₂**
