my answer is E, if I am wrong, feel free to correct me
from June 25, 1982 to June 25, 1987 is exactly 5 years, 1984 was a leap year, so you can work out the total number of days during the five years, 5*365+1
then there are seven days a week, so 5*365+1 divides by 7, the residue is 6,  6 days after Friday is Thusday

upstairs,how you got the residue 6?

5*365+1=1826

1826/7=260.857
