Solution:

Nucleus is a double membrane bound organelle 1st discovered by Robert Brown and stores the DNA of cell. The double membrane of the nucleus, nuclear envelope, has space within it called as perinuclear space. These membranes fuse at certain points around the nucleus giving rise to nuclear pores which help in exchange of substances between nucleus and cytoplasm. Interphase is one of the phases of cell cycle where the DNA is folded with the help of protein resulting is a structure called chromatin which was named by Flemming. Therefore, statement I and IV are true and remaining two are false.
