For option B (T1,T2,T3)=(20,10,30) which means we first execute T2, then T1 , then T3 at last. Given schedules:- If we follow option B:- This would be as we see the actual schedule the final write for B(W(B)) must be done T2 but if we follow option option B it is done by T3 which is inconsistent. 0 votes 0 votes Karishma Datt commented Jul 24, 2022 reply Follow Share yes 0 votes 0 votes Shubham Sharma 2 commented Jul 24, 2022 i edited by Shubham Sharma 2 Jul 24, 2022 reply Follow Share got it, thanks @Kabir5454 1 votes 1 votes vishnu777 commented Nov 21, 2022 reply Follow Share What is the correct answer?? 0 votes 0 votes Please log in or register to add a comment.
