Java man (Homo erectus erectus) is the popular name given to early human fossils discovered on the island of Java (Indonesia).

Cro-Magnon man is a common name that has been used to describe the first early modern humans (early Homo sapiens sapiens) that lived in the European Upper Paleolithic. Cro-Magnons were robustly built and powerful. The body was generally heavy and solid with a strong musculature. The forehead was fairly straight rather than sloping like in Neanderthals, and with only slight brow ridges. The face was short and wide. The chin was prominent. The brain capacity was about 1,600 cubic centimetres (98 cu in), larger than the average for modern humans.

A base analog is a chemical that can substitute for a normal nucleobase in nucleic acids. They are categorized into two separate groups, purine analogues and pyrimidine analogues. One of the more common base analogs is 5-bromouracil (5BU). When a nucleotide containing 5-bromouracil is incorporated into the DNA, it is most likely to pair with adenine; however, it can spontaneously shift into another isomer which pairs with a different nucleobase, guanine. If this happens during DNA replication, a guanine will be inserted as the opposite base analog, and in the next DNA replication, that guanine will pair with a cytosine. This results in a change in one base pair of DNA, specifically a transition mutation.

The inheritance of acquired characteristics is a hypothesis that physiological changes acquired over the life of an organism (such as the enlargement of a muscle through repeated use) may be transmitted to offspring. It is also commonly referred to as the theory of adaptation equated with the evolutionary theory of French naturalist Jean-Baptiste Lamarck known as Lamarckism.

So, the correct answer is option A.
