C Correct answer
Explanation

Allows cytoplasmic proteins to enter the nucleus. In the nucleus, important activities as DNA replication, transcription, etc. take place. These are initiated and mediated by many enzymes that are produced inside the cell. Therefore, the enzymes are transported from cytoplasm to nuclear matrix through nuclear pore.
