The correct Answer is:
**Step-by-Step Solution:** 1. **Identify the Type of Hormones**: The question asks about gibberellins (also known as gibberellic acids). These are a type of plant hormone that promotes growth. 2. **Understand the Nature of Gibberellins**: Gibberellins are classified as plant growth regulators. They can be categorized into two types: promoters and inhibitors. Gibberellins fall under the category of promoter hormones. 3. **Recognize the Discovery of Gibberellins**: There are over 100 different gibberellins identified, which are denoted as GA1, GA2, GA3, and so on. The first gibberellin discovered was GA3, also known as gibberellic acid. 4. **Determine the Chemical Nature of Gibberellins**: It is important to note that all gibberellins are acidic in nature. This is a key characteristic that defines them. 5. **Summarize the Functions of Gibberellins**: Gibberellins are responsible for various growth-promoting activities, including: - Increasing internodal length. - Promoting seed germination. - Speeding up the malting process in brewing industries. - Facilitating bolting (the rapid growth of flowering stems) in certain plants. 6. **Conclude the Answer**: Based on the information gathered, the correct answer to the question "All gibberellins are" is that they are **acidic**. **Final Answer**: All gibberellins are acidic. ---
