Answer

To solve the question regarding the properties of Allium cepa (onion), we need to analyze the given options and identify which statement is incorrect about this plant. Here’s a step-by-step breakdown:

### Step 1: Understand the Classification
Allium cepa is the scientific name for the onion, which belongs to the family Liliaceae (lily family). This family is characterized by certain morphological features.

**Hint:** Familiarize yourself with the classification of Allium cepa and its family characteristics.

### Step 2: Analyze the Properties
We need to evaluate the properties mentioned in the options:

1. **Simoes Inflorescence and Umbilate Clusters**: This is correct. In the Liliaceae family, flowers are arranged in a simoes type of inflorescence, where the floral axis terminates in a flower, and flowers are grouped in clusters.

2. **Aerial Part Dies, Bulb Survives**: This is also correct. In unfavorable conditions, the aerial part of the onion plant may die, but the bulb (a modified underground stem) survives and can regenerate when conditions improve.

3. **Three Green Sepals and Three Pink Petals**: This statement is incorrect. In the Liliaceae family, the flowers do not have distinct sepals and petals. Instead, they have a structure called perianth, which consists of tepals. Typically, there are three outer and three inner tepals, not separate sepals and petals.

4. **Same Family as Colchicum autumnale**: This is correct. Both Allium cepa and Colchicum autumnale belong to the Liliaceae family.

**Hint:** Carefully evaluate each property against the known characteristics of the Liliaceae family.

### Step 3: Identify the Incorrect Property
From the analysis, the incorrect property is the one stating that Allium cepa has three green sepals and three pink petals. Instead, it has tepals that are not classified as separate sepals and petals.

### Conclusion
The property that is not found in Allium cepa is: **"There are three green sepals and three pink petals."**

**Final Answer:** Option C is the incorrect statement regarding Allium cepa.
