Answer:
Option D
Explanation:
Clearly, S must be released on fifth Friday. P must be released a week before T i.e., order PT must be followed. But T cannot be released in the last. Also, Q must be released immediately after U i.e. order UQ must be followed. But Q cannot precede S. So, U and Q can be released on first and second Fridays respectively and P and T on third and fourth Fridays respectively. R, which cannot be released on Second Friday, shall be released last. Thus, the order followed will be U, Q, R T, S, R.
R can not be released on the fifth Friday as well because S has to be staged on that day.
