Verified step by step guidance

1. Understand that the question asks for the approximate current population size of the United States, which is a demographic fact rather than a calculation problem.
2. Recall that the population of the United States is measured in millions, not billions, since the total world population is about 8 billion.
3. Recognize that 1.2 billion and 3.35 billion are much larger than the actual U.S. population and are closer to global population scales.
4. Compare the remaining options: 33.5 million is too low for the U.S., which is known to have a population in the hundreds of millions.
5. Conclude that the most reasonable and widely accepted estimate for the U.S. population is about 335 million people.
