Please help me to get the above result

Answer 1

Try this (edited):

select t1.Name, t1.Subject, max(month) as Latest_Month_Attended, t2.year as Latest_Year_Attended
from tab t1
join (
    select Name, Subject, max(year) as year
    from tab
    group by Name, Subject
) t2 on t1.name = t2.name and t1.subject = t2.subject and t1.year = t2.year
group by t1.Name, t1.Subject, t2.year
