Amoeba moves with the aid of :
(a) pseudoplasmodium
(b) pseudopodia
(c) cilia
(d) flagella

Options

A. pseudoplasmodium
B. pseudopodia
C. cilia
D. flagella

Explanation

To answer the question "Amoeba moves with the aid of:", we will analyze the options provided:

1. **Understanding Amoeba**:
- Amoeba is a unicellular eukaryotic organism that belongs to the group of protozoa. It is known for its unique way of movement and feeding.

2. **Analyzing the Options**:
- (a) **Pseudoplasmodium**: This term refers to a temporary structure formed by some slime molds during their life cycle and is not related to amoeba movement.
- (b) **Pseudopodia**: These are temporary arm-like projections of the cell membrane and cytoplasm that amoebas extend to move and capture food. This is the primary means of locomotion for amoeba.
- (c) **Cilia**: These are short, hair-like structures that cover some cells and help in movement, but amoeba does not use cilia for movement.
- (d) **Flagella**: These are long, whip-like structures that some organisms use for movement, but amoeba does not have flagella.

3. **Conclusion**:
- The correct answer is (b) **pseudopodia**. Amoeba moves using pseudopodia, which are extensions of its cytoplasm that allow it to crawl and capture food.

### Final Answer:
(b) pseudopodia
