The correct Answer is:
To solve the question regarding which group of protozoans have chambered and perforated shells that develop reticulate pseudopodia, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks about protozoans that have specific characteristics: chambered and perforated shells, as well as reticulate pseudopodia. 2. **Identify the Options**: The options given are: - A. Amoeboid - B. Radiolarians - C. Heliozoans - D. Foraminiferans 3. **Analyze Each Option**: - **Amoeboid**: This is a broader classification that includes various types of protozoans, but it does not specifically refer to the characteristics mentioned in the question. - **Radiolarians**: These protozoans have silica-based shells but do not have chambered shells. Therefore, they do not fit the description. - **Heliozoans**: They possess stiff pseudopodia and do not have the chambered shells described in the question, making them an incorrect choice. - **Foraminiferans**: These protozoans are known for their chambered and perforated shells, and they develop reticulate pseudopodia. This matches the description provided in the question. 4. **Conclusion**: Based on the analysis, the correct answer is **D. Foraminiferans**. They are characterized by their chambered and perforated shells and reticulate pseudopodia. ### Final Answer: **D. Foraminiferans**

Sulphur and rest of the elements of group 16 are less electronegative than oxygen, Therefore, their atoms cannot take electrons easily. They can acquire ns^2 np^6 configuration by sharing two electrons with the atoms of other elements and thus, exhibit +2 oxidation state in their compounds. In addition to this, their atoms have vacant d-orbitals in their valence shell to which electrons can be promoted from the p and s-orbitals of the same shell. As a result, they can show +4 and + 6 oxidation states. Oxygen exhibits +2 oxidation state in
