Select the FIRST correct reason why the given series diverges. A. Diverges because the terms don't have limit zero B. Divergent geometric series C. Divergent p series D. Integral test E. Comparison with a divergent p series F. Diverges by limit comparison test G. Diverges by alternating series test Comparison test: Suppose there is a fixed number K such that for all sufficiently large n: i} D fin > i} and (1 lim _n = R exists.
