C. 6-amino-2-imino-4-carbamylhexanamide
D. None of the above

Explanation

To determine the IUPAC name of the given compound, we will follow a systematic approach. Here’s a step-by-step solution:

### Step 1: Identify the Parent Chain
The first step is to identify the longest continuous carbon chain in the compound. In this case, the chain can be traced as follows:
- Start from the leftmost carbon and move to the right.
- The longest chain consists of 5 carbon atoms.

### Step 2: Number the Carbon Chain
Next, we need to number the carbon chain. The numbering should be done in such a way that the substituents (functional groups) receive the lowest possible numbers:
- Number the chain from the end closest to the first substituent (amide group).
- This gives us the following numbering:
1. CH2
2. C
3. CH
4. CH2
5. C

### Step 3: Identify and Name the Substituents
Now we need to identify the substituents attached to the parent chain:
- At position 1, there is an amide group (–CONH2).
- At position 2, there is another amide group (–CONH2).
- At position 4, there is a third amide group (–CONH2).

### Step 4: Combine the Names of the Substituents
Since there are three amide groups, we will use the prefix "tri-" to indicate that there are three identical substituents. We will also specify their positions:
- The amide groups are at positions 1, 2, and 4.

### Step 5: Write the Complete IUPAC Name
Now, we can combine all the information to write the full IUPAC name:
- The base name for the 5-carbon chain is "pentane."
- The substituents will be named as "1,2,4-tricarboxamide" since each amide group is a carboxamide.

Thus, the complete IUPAC name of the compound is:
**1,2,4-triaminopentane-1,2,4-tricarboxamide**

### Final Answer
The IUPAC name of the compound is **1,2,4-triaminopentane-1,2,4-tricarboxamide**.
