D. Do not flower in any photoperiod.

Answer

### Step-by-Step Solution:

1. **Definition of Day Neutral Plants**:
- Day neutral plants are those that do not rely on the length of daylight or darkness to flower or grow. This means their growth and flowering are not influenced by the photoperiod (the duration of light and dark periods).

2. **Characteristics**:
- These plants can flower and grow regardless of whether the days are long or short, or whether the nights are long or short. Their growth is independent of the light conditions.

3. **Examples**:
- Common examples of day neutral plants include:
- Sunflower (Helianthus annuus)
- Tomato (Solanum lycopersicum)
- These plants can thrive and produce flowers in various light conditions.

4. **Conclusion**:
- The key takeaway is that day neutral plants can flower in all possible photoperiods, meaning they are versatile in their growth and do not require specific light conditions to thrive.
