Answer:
Cde
Step-by-step explanation:
Because if you look at abcdefghi, In programming you start with 0. So it would be a:0 b:1 c:2 d:3 e:4 f:5 g:6 h:7 i:8. So if you say 2:5, it would be from c to e. Because in programming you dont count the last letter which is 5 you use the letter right before 5 to end it. Sorry its a bit confusing. But im 100% sure its right.
