The Correct Option is B

Solution and Explanation


Step 1: Concept

The nucleus is a specialized organelle that contains specific sub-structures related to genetic material processing.

Step 2: Analysis

The nucleolus (site of rRNA synthesis) and paraspeckles (lncRNA-rich nuclear bodies) are localized within the nucleoplasm.

Step 3: Meaning

The Golgi body, Mitochondria, and Endoplasmic reticulum are distinct organelles located in the cytoplasm outside the nuclear envelope.

Step 4: Conclusion

Therefore, B, D, and E are the structures not present inside the nucleus. Final Answer: (B)
