The correct answer will be option-C
Explanation:
LUCA or the last universal common ancestor or the concestor represents one of the populations of the most common ancestor of all the organisms present on this Earth today.
The LUCA organisms are not considered the first form of life on earth but studies show that they spread their genes to all other organisms through horizontal transfer methods.
Recent studies by William F. Martin indicates that LUCA was anaerobic thermophilic, H₂-dependent, CO₂-fixing organisms, therefore, the correct answer is option-C.
