is truth that most of the unicellular organisms like bacteria, are
among the simplest life forms we know about it, but there are many

Answer:
First, lets add the missing piece of information
a. He worked on the manuscript for three years.
b. It was successful.
c. It explained his theory of evolution.
d. It was based on his findings in South Africa.
The CORRECT ANSWER IS d.
d. It was based on his findings in South Africa.
Explanation:
On the Origin of Species was a book which main focus and central theme was focused on the observations that Charles Darwin noticed on the Galapagos Islands, which is in proximity and closeness to today's Ecuador - west of South America. The option d "it was based on his findings in South Africa." Is absolutely wrong since the study wasn't carried out in South Africa - as South Africa is a totally different continent.
