Which of the following is a rapid type of water absorption?

Options

A. Active absorption
B. Passive absorption
C. Continuous absorption
D. Pulsationg absorption

Answer

**Step-by-Step Solution:**

1. **Understanding Water Absorption Types**: Water absorption in plants can be categorized into two main types: active absorption and passive absorption.

2. **Identifying the Options**: The options given are:
- Active absorption
- Passive absorption
- Continuous absorption
- Pulsating absorption

3. **Eliminating Incorrect Options**:
- Continuous absorption and pulsating absorption are not recognized types of water absorption in plants. Therefore, we can eliminate these two options.

4. **Analyzing Active Absorption**:
- Active absorption requires energy to occur. It involves the movement of water against the concentration gradient, meaning water moves from an area of lower concentration to an area of higher concentration. This process is generally slow due to the energy requirement.

5. **Analyzing Passive Absorption**:
- Passive absorption does not require energy. Water moves from an area of higher concentration to an area of lower concentration, following the concentration gradient. This process is rapid because it relies on natural diffusion.

6. **Conclusion**: Since passive absorption is the process that occurs quickly and does not require energy, it is identified as the rapid type of water absorption.

**Final Answer**: The rapid type of water absorption is **Passive Absorption**.
