D. 4-Amino-4-methylpentan-2-one

Explanation

To determine the IUPAC name of the given compound `(CH3)2-NH2-C-CH2-CO-CH3`, we will follow these steps:

### Step 1: Draw the Structure
First, we need to convert the condensed formula into a structural formula. The compound consists of:
- Two methyl groups `(CH3)2` attached to a carbon.
- An amine group `NH2` attached to the same carbon.
- A `CH2` group connected to the carbon chain.
- A carbonyl group `CO` (which indicates a ketone) followed by another `CH3` group.

The structural representation will look like this:
```
NH2
|
CH3-C-CH2-CO-CH3
|
CH3
```

### Step 2: Identify the Longest Carbon Chain
Next, we need to identify the longest continuous carbon chain. In this case, the longest chain consists of 5 carbon atoms:
```
C1 - C2 - C3 - C4 - C5
```
This chain is the parent chain.

### Step 3: Identify Functional Groups and Substituents
- The functional group present is a ketone (`-CO-`), which gives it higher priority.
- The amine group (`NH2`) and the two methyl groups (`CH3`) are substituents.

### Step 4: Number the Carbon Chain
We will number the carbon chain starting from the end closest to the functional group (the carbonyl). This gives us:
```
1 - 2 - 3 - 4 - 5
```
Where:
- C2 has the ketone functional group.
- C4 has the amine substituent.
- C4 also has a methyl substituent.

### Step 5: Write the Parent Name
The parent chain has 5 carbons, which corresponds to "pentane." Since it has a ketone functional group, we will use the suffix `-one`. The ketone is on carbon 2, so we write "pentan-2-one."

### Step 6: Write the Substituent Names
- The amine group is on carbon 4, so we denote it as "4-amino."
- The methyl group is also on carbon 4, denoted as "4-methyl."

### Step 7: Combine the Names
According to IUPAC naming conventions, we list the substituents in alphabetical order followed by the parent name:
- "amino" comes before "methyl."
Thus, we write:
- 4-amino-4-methyl-pentan-2-one

### Final Answer
The IUPAC name of the given compound is **4-amino-4-methyl-pentan-2-one**.
