Answer:

B

Explanation:

Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.

Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.
