To identify the author's opinion among the given statements, we need to analyze the language used in each statement and look for subjective statements or statements that express a viewpoint. Let's examine each statement:

a. Olmsted - was appoint superintendent and worker began cleaning the land for construction.
This statement appears to be a factual statement without any clear opinion or subjective viewpoint.

b. After a vote by park commissioner, Vaux and Olmsted become the officer design of Central Park.
This statement also seems to be a factual statement about the appointment of Vaux and Olmsted as the official designers of Central Park. It does not express any opinion.

c. Calvert Vaux, a British architect who has helped design the grounds of the White House and the Smithsonian Institution, asked Olmsted to collaborate with him.
Similar to the previous statements, this statement provides factual information about Calvert Vaux's architectural background and his collaboration with Olmsted. It does not express any subjective opinion.

d. Olmsted and Vaux work of art welcome about 40 million visitors each year.
This statement appears to be a subjective statement, as it uses the phrase "work of art" to describe the impact of Olmsted and Vaux's work on Central Park and states that it "welcomes about 40 million visitors each year." The use of the term "work of art" suggests that the author has a positive opinion about their contribution to the park.

In conclusion, the statement that reflects the author's opinion is option d: "Olmsted and Vaux work of art welcome about 40 millions visitors each year."
