Therefore, Darwin, his theory of evolution and its acceptance is common to the three.
Another way to determine the sequence is to follow the sequence of the years mentioned in D, A and C.
D talks about Darwin’s theory which was published in 1859,
A states that by 1870s, people started to accept his theories,
And C mentions that a broad consensus developed in the 1930s.
Facts/statements are usually mentioned in chronological order. So, it is also a way to determine the sequence.
We know that B cannot precede D. We also know that A and C follow A respectively.
Therefore, the order is DACB
