Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Option A, is correct. Option B need not necessarily be true, because (an) could consist of negative terms. Counterexample for Option C, consider the sequence of partial sums of the series ((-1)^n)/n. Check whether the modulus of this is convergent.
![eduncle-logo-app]()
its modulus is convergent s1=1 s2=1/2 s3=1/3....it is monotonically decreasing and bounded below by 0 hence converge to 0
![eduncle-logo-app]()
sequence of partial sum of (-1)^n/n is itself not converging u cant take this...according to me
![eduncle-logo-app]()
It's modulus is not convergent. Also, I did give the right example, you can check. The series is conditionally convergent. That's why it works.
