Use the nth-term test for divergence to show that the series is divergent, or state that the test is inconclusive. > cos n=1 Choose the correct answer below. O A. The series diverges because lim cos exists and is equal to n00 O B. The test is inconclusive because lim cos n00 Oc. The series diverges because lim cos = 0o and fails to exist n00 The series diverges because lim cos 0o and fails to exist O D. n00 %3D
