Answer

To determine what a corm is a modification of, we can follow these steps:

### Step 1: Understand the Definition of a Corm
A corm is defined as a solid, fleshy underground structure that serves as a storage organ for plants.

**Hint:** Look for the characteristics of a corm to identify its type.

### Step 2: Identify the Type of Plant Structure
Since a corm is an underground structure, we need to classify it among the main plant structures: roots, stems, leaves, and seeds.

**Hint:** Consider the function of the corm and where it is located in relation to the plant.

### Step 3: Analyze the Functions of Corms
Corms are primarily used for the storage of food and nutrients, which is a characteristic feature of modified stems.

**Hint:** Think about which part of the plant is typically involved in storage functions.

### Step 4: Compare with Other Options
- **Roots:** While roots can store food, they are not fleshy and solid like corms.
- **Leaves:** Leaves are primarily for photosynthesis and not for storage.
- **Seeds:** Seeds are reproductive structures, not storage organs like corms.

**Hint:** Eliminate options that do not fit the definition and function of a corm.

### Step 5: Conclusion
Based on the definition and functions discussed, we conclude that a corm is a modification of the stem.

**Final Answer:** Corm is a modification of the stem (Option C).
