It depends entirely on how the question is read. If the question is asking what is the largest religion that is still growing, the answer would be Christianity since there are more and more Christians born and converted every day than convert out or die. If the question is asking what religion is growing by the largest numbers of new followers (both births and converts), then the answer would be Islam, since the population growth in Muslim-majority countries has made Islam the religion with the most new adherents daily. If the question is asking what religion has the greatest percentage of growth, then this would be a contest between a number of very small religions which have high percentage increases, but low current population counts, such as Baha'i or Jehovah's Witnesses. Although these cannot match the numerical growth of Christianity or Islam, the thousands of converts and newborns have a much higher relative to the <20 million adherents to the religion.
