The correct option is
B Cro-Magnon man
It has been known as Cro- Magnon man, because its fossils were first discovered in 1868 from Cro-Magnon rocks of France by MacGregor. Cro-Magnon man emerged about 34000 years ago in Holocene epoch. Thus, it is regarded as most recent ancestor of today's man. The Cro-Magnon man had, like us, about 1.8 metres tall, well-built body. Its face was perfectly orthognathous (jaws do not project forward) with an arrow, elevated nose, broad and arched forehead, moderate brow ridges, strong jaws with man-like dentition and a well developed chin. Its cranial capacity was, however, somewhat more than ours, being about 1650 cc. It is, therefore, believed that Cro Magnon man was somewhat more intelligent and cultured than the man of today. It could walk and run faster and lived in families in caves. It made excellent tools and even ornaments, not only of stones and bones, but also of elephant tusks. Its tools included spears, bows and arrows, as he was omnivorous. Use of the skin clothes by this man is also confirmed. So, the most nearest prehistoric ancestor of present man may be Cro-magnon man compared to Java man, neanderthal man and Peking man.
Therefore, the correct answer is option B.
