Answer

To determine the characteristics of entomophilous flowers, we need to understand what entomophily means. Entomophilous flowers are those that are pollinated by insects. Here’s a step-by-step breakdown of the characteristics of these flowers:

### Step 1: Understanding Entomophily
- **Definition**: Entomophily refers to the pollination of flowers by insects. Common pollinators include bees, butterflies, and moths.

### Step 2: Characteristics of Entomophilous Flowers
1. **Colorful**:
- Entomophilous flowers are often brightly colored to attract insects. The vibrant colors serve as visual cues for pollinators.

2. **Fragrant**:
- These flowers typically emit pleasant fragrances that attract insects. The scent acts as an additional lure for pollinators.

3. **Nectar-rich**:
- Entomophilous flowers produce nectar, which is a sugary liquid that provides food for insects. This is a key characteristic, as the presence of nectar encourages insects to visit the flowers for feeding, thus facilitating pollination.

4. **Large Size**:
- Many entomophilous flowers are larger in size, making them more noticeable to insects.

### Step 3: Evaluating the Options
Now, let's evaluate the options given in the question:
- **Option 1**: Nectarless, odorless, and colored - Incorrect (should be nectar-rich and fragrant).
- **Option 2**: Colorful, fragrant, and nectar-rich - Correct (matches the characteristics).
- **Option 3**: Colored, fragrant, and nectarless - Incorrect (should be nectar-rich).
- **Option 4**: Coated by a waxy layer - Incorrect (not a characteristic of entomophilous flowers).

### Conclusion
The correct answer is **Option 2: Colorful, fragrant, and nectar-rich**.
