Answer 1

Hint: Apes are human’s closest living relatives. And additionally, humans and apes have more in common than most other animals because we had common ancestors millions of years ago. This is the reason why apes and humans have characteristics that are very similar.

Complete step-by-step answer:
Evolution causes the change in the genetic characteristics from one generation to the other. The maximum use of a certain organ in a period of evolution causes their development. The modern man varies from the apes in arms shorter than legs. In apes, the arms help in the locomotion known as trachiation, a kind of suspension and swinging of the body. The arms of the apes developed more in modern people in course of evolution to adapt to the changing environment. Apes had equal size of arms with legs, but modern people are having arms and shorter legs that differ from apes. Apes have muscles and bones like humans. Their nervous system works just as it does in humans. Apes and humans have an equal number of fingers and toes. The structure of the human female uterus resembles a female ape. Both humans and apes have an almost alike lifespan. Opposable thumbs are something that apes and humans, both of them have in common. Though not identical, apes have blood types similar to the human ABO blood group system. Both female humans and female apes have regular menstrual cycles.

Therefore the correct answer is Option A.
Note: Humanity's closest living relatives are Apes. In fact, humans share around 98% of their DNA with chimpanzees, and hence, people are actually apes. The non-human kinds of apes are generally split into two groups: Great Apes- Orangutans, bonobos, chimpanzees, lesser apes siamangs, gorillas, and gibbons.
