Best answer
Right option is (d) They are present during interphase and absent during mitosis.

Explanation: Paraspeckles are irregular shaped sub-nuclear compartments which are transcription dependent.  Paraspeckles disappear in absence of RNA polemerase II transcription and all of its associated protein components form a crescent shaped perinucleolar cap in the nucleolus. However, paraspeckles are present during the interphase and all the stages of mitosis except the telophase.
