B. II alone is sufficient while I alone is not sufficient.

D. Neither I nor II is sufficient.
E. Both I and II are sufficient.

Answer: Option E

Explanation:

From I, we know that the serial were screened on 23rd, 24th, 25th and 26th.

Clearly, D was screened second i. e. on 24th, Wednesday.

From II, we know that one serial was screened between A and B. So, A and B were screened first and third, i. e. on 23rd and 25th. But, A was not screened on 25th.

So, A was screened on 23rd and B on 25th. Thus, C was screened on 26th, Friday.
