The correct option is
C Pithecanthropus erectus
- Evolution is a slow process that leads to gradual variation in the attributes of the living organism.
- Java ape Man (Homo erectus Erectus) is the popular name given to early human fossils discovered on the island of Java (Indonesia) in 1891 and 1892.
- Led by Eugene Dubois, the excavation team uncovered a tooth, a skullcap, and a thighbone at Trinil on the banks of the Solo River in East Java. Arguing that the fossils represented the "missing link" between apes and humans, Dubois gave the species the scientific name Anthropopithecus Erectus, then later renamed it Pithecanthropus erectus.
Therefore, the correct answer is option A.
