Answer:
The correct answer is letter "A": Almost half of all U.S. firms are small businesses.
Explanation:
According to a research conducted in 2016 by the U.S. Small Business Administration (SBA), there are 28.8 million small businesses in the U.S. representing 99.7% of the total number of companies in the country.
Small businesses employ around 56.8 million workers nationwide but the problem relies on the time the organizations can keep their operations up and running since only one-third of small businesses survive longer than 10 years.
