Solution

1.

D. D is correct statement about archaea

Archaea are ancient bacteria that are the ancestors of Eukarya

It has been hypothesized that the archaea evolved from gram-positive bacteria in response to antibiotic selection pressure. Because archaea are resistant to a wide variety of antibiotics that are primarily produced by gram-positive bacteria.

And they having trancrription and translation machinery similar to eukaryote so that indicating that they are ancestor of eukaryote

2

option D is correct Bacteria differ from eukaryotes in having no nucleus, mitochondria, or chloroplasts, but, like all cells, have ribosomes.
