D. Sorbitol

Explanation

To determine the compound represented by the condensed formula `HO-CH_2-(CHOH)_4-CH_2OH`, we will analyze the structure step by step.

### Step 1: Identify the Structure
The given formula can be broken down as follows:
- The `HO-` at the beginning indicates a hydroxyl (-OH) group attached to a carbon.
- The `CH_2-` indicates a carbon atom bonded to two hydrogen atoms.
- The `(CHOH)_4` indicates that there are four carbon atoms, each bonded to a hydroxyl group (-OH).
- The `-CH_2OH` at the end indicates another carbon atom bonded to two hydrogen atoms and a hydroxyl group.

### Step 2: Count the Carbon Atoms
From the structure:
- The first `CH_2` contributes 1 carbon.
- The four `CHOH` groups contribute 4 carbons.
- The last `CH_2OH` contributes 1 carbon.
- Total carbon atoms = 1 + 4 + 1 = 6 carbon atoms.

### Step 3: Count the Hydrogen Atoms
Now, we will count the hydrogen atoms:
- The first `CH_2` contributes 2 hydrogens.
- Each `CHOH` contributes 1 hydrogen (4 groups contribute 4 hydrogens).
- The last `CH_2OH` contributes 2 hydrogens.
- Total hydrogen atoms = 2 + 4 + 2 = 8 hydrogen atoms.

### Step 4: Count the Oxygen Atoms
Next, we will count the oxygen atoms:
- There are two hydroxyl groups (one at the beginning and one at the end) and four from the four `CHOH` groups.
- Total oxygen atoms = 2 + 4 = 6 oxygen atoms.

### Step 5: Write the Molecular Formula
Now we can write the molecular formula based on the counts:
- Carbon (C) = 6
- Hydrogen (H) = 14
- Oxygen (O) = 6
- Therefore, the molecular formula is C6H14O6.

### Step 6: Identify the Compound
Now we need to identify what compound corresponds to this molecular formula.
- The structure and formula match that of **Sorbitol**, which is a sugar alcohol derived from glucose.

### Conclusion
The compound represented by the condensed formula `HO-CH_2-(CHOH)_4-CH_2OH` is **Sorbitol**.
