Answer:

d. chromatin

Explanation:

Chromatin is a complex of DNA, RNA, and proteins that is present in the eukaryotic cell nucleus in the form of a long, spaghetti-like filament. Histones are the main proteins that make up the chromatins.

Chromatin is usually divided into two categories according to their condition: eucromatin and heterochromatin.

Eucromatin: When the chromatin filaments are less condensed it means that it has active DNA, ie the cell is able to "read" the content of this genetic material.
Heterochromatin: The filaments are condensed, coiled together in a tangle. In this case, the DNA is inactive because cells at that time are unable to encode the condensed genetic material.

Some helpful tips:

The nucleus is always going to be the big, spherical shape.

The ER is always going to be a weird, folded looking structure attached to the nucleus (rough = has ribosomes on it which are usually represented by little dots, smooth = has no ribosomes on it aka no dots)

The GA looks like the ER but it is not going to be attached to the nucleus like the ER is.

The mitochondria is always going to be pill-shaped and have weird folds inside of it.
