Answer:
The correct answer is D. 4,000 students attended the college in 2014.
Step-by-step explanation:
In 2015, the College had a total student body of 4,200, which was 5% more than in 2014. So, in order to know how many students were part of the student body in 2014, we have to do the following calculation: 4,200 / 1.05 = 4,000. Therefore, in 2014, 4,000 students attended the college.
