Final answer:

Eukaryotic cells evolved from ancient prokaryotic cells through endosymbiotic events, making both bacterial and archaean prokaryotic cells the examples of primitive cells from which eukaryotes descended.

Step-by-step explanation:

The question you've asked is about the origin of eukaryotic cells and which type of cells are considered examples of primitive cells. The most widely accepted theory for the origin of eukaryotic cells is the endosymbiotic theory, which suggests that these cells are derived from ancient prokaryotic cells. According to this theory, eukaryotic cells arose from the engulfment of an aerobic bacterium (which became mitochondria) and sometimes a photosynthetic bacterium (which became chloroplasts) by a larger host prokaryotic cell. The host cell is believed to be more closely related to archaean prokaryotic cells .

In the context of the choices provided, the examples of a primitive cell would therefore be both bacterial and archaean prokaryotic cells (option d). These cells evolved over eons and are the ancestors from which eukaryotic cells are thought to have descended. Archaebacteria, unlike eubacteria, are considered to have given rise to eukaryotes following endosymbiotic events, leading to the development of complex cellular structures and eventually multicellularity.
