Options

A. frogs
B. Birds
C. Lizards
D. AII

Answer

To determine which organisms are seasonal breeders, we need to analyze the breeding patterns of the given options: frogs, birds, and lizards. Seasonal breeders are organisms that reproduce during specific seasons rather than throughout the entire year.

### Step-by-Step Solution:

1. **Understanding Seasonal Breeding**:
- Seasonal breeders are organisms that have a specific time of year when they reproduce. This is often linked to environmental factors such as temperature, food availability, and day length.

2. **Analyzing Frogs**:
- Frogs typically breed in early spring. This is the time when conditions are favorable for their reproduction. They do not reproduce throughout the year, making them seasonal breeders.

3. **Analyzing Birds**:
- Birds generally have a breeding season that spans from mid-June to September. During this period, they engage in mating and raising their young. Outside of this time frame, they do not reproduce, categorizing them as seasonal breeders as well.

4. **Analyzing Lizards**:
- Lizards also tend to breed in the spring season. Similar to frogs and birds, their reproduction is confined to a specific time of year, which qualifies them as seasonal breeders.

5. **Conclusion**:
- Based on the analysis, all three organisms—frogs, birds, and lizards—are seasonal breeders. Therefore, the correct answer includes all of these options.

### Final Answer:
Frogs, birds, and lizards are all seasonal breeders.
