According to Wikipeia:
<<In descriptive statistics, a quartile is any of the three values which divide the sorted data set into four equal parts, so that each part represents 1/4th of the sampled population.
Thus:
first quartile (designated Q1) = lower quartile = cuts off lowest 25% of data = 25th percentile >>
So the correct answer is A)
