Use the nth-term test for divergence to show that the series is divergent, or state that the test is inconclusive. 16 COS n n=1 Choose the correct answer below. ok 16 O A. The series diverges because lim cos exists and is equal to n n- 00 16 O B. The test is inconclusive because lim cos n n-100 urce 16 O C. The series diverges because lim cos = - co and fails to exist. n-+co n ources 16 O D. The series diverges because lim cos -= co and fails to exist. n ons on Tools
