Answer:
C. Photoautotrophs-oxygenic.
Explanation:
LUCA is an abbreviation of the ‘Last Universal Common Ancestor’. The LUCA was a microorganism which lived around 4 billion years ago. The evidence had shown that the LUCA was lived deep underground in hydrothermal vents. These vents were rich in iron-sulphur. It did not use air but made its food from the metal-rich environment surrounding it. It made organic compounds such as ammonia for its metabolism from elements such as hydrogen, carbon dioxide and nitrogen.

Enzymes are made of proteins
that are capable of catalyzing a reaction in which various substrate are
converted to products through the formation of an intermediate enzyme-substrate
complex. It hastens reactions and acts as a catalyst without themselves
undergoing permanent chemical changes. The catalytic ability of enzymes is due
to its particular protein structure.
A. Mitosis always results in 2 identical daughter cells containing 2n chromosomes. 2n chromosomes is considered diploid. The next step in your question is the splitting of the cell into the two identical daughter cells.
