Answer :

To determine the percentage of U.S. GDP in 2016 that came from the arts and culture industries, we need to look at the given options and identify the correct one.

Here are the options provided:
- A. 4.3%
- B. 50%
- C. 5 million
- D. 3.4%

First, we can eliminate option C, 5 million, as it is not presented as a percentage, which is what we are seeking.

Next, we consider the remaining percentage options. Fifty percent (B) is highly unlikely because it represents half of the entire GDP, which is disproportionately large for a single sector.

Now, we have narrowed it down to two plausible options: 4.3% (A) and 3.4% (D).

Given the correct percentage, we can now confidently state that the arts and culture industries contributed 3.4% to the U.S. GDP in 2016.

Thus, the correct answer is:
D. 3.4%
