D. Aminoacetone

Explanation

To solve the question regarding the compound with the formula `(CH3)2NH2C(CH2)COCH3`, we need to identify the compound and determine the degree of the amine. Here’s a step-by-step solution:

### Step 1: Analyze the Given Structure
The compound is represented as `(CH3)2NH2C(CH2)COCH3`. We can break this down into its components:
- The `(CH3)2` indicates there are two methyl groups attached to a nitrogen atom.
- The `NH2` indicates the presence of an amino group.
- The `C(CH2)COCH3` indicates a carbon chain with a carbonyl (C=O) group.

### Step 2: Identify the Compound
From the breakdown, we can see that the compound has:
- Two methyl groups attached to the nitrogen (indicating it is likely a derivative of an amine).
- A carbon chain that includes a carbonyl group, which suggests it is a ketone.

This structure matches the description of **diacetone amine**, which is derived from acetone.

### Step 3: Determine the Degree of the Amine
To determine the degree of the amine:
- A primary amine (1°) has one alkyl group and two hydrogens attached to nitrogen.
- A secondary amine (2°) has two alkyl groups and one hydrogen attached to nitrogen.
- A tertiary amine (3°) has three alkyl groups and no hydrogens attached to nitrogen.

In our case, the nitrogen is attached to two methyl groups (from `(CH3)2`) and one carbon chain (NH2), which means it has one hydrogen left. Therefore, it is classified as a **primary amine**.

### Final Answer
The compound `(CH3)2NH2C(CH2)COCH3` is **diacetone amine**, and it is a **primary amine**.
