Answer 1

Correct Answer - Option 1 : t, s, r, s

By checking the following alternatives:

1) t, s, r, s → rrstssr/rrstssr/rrstssr (followed the pattern)

2) t, s, s, r → rrstssr/rrstssr/srstrsr 

3) s, t, t, r → rrssssr/rrttssr/trstrsr

4) r, r, s, t → rrsrssr/rrrtssr/srsttsr 

Hence, 't, s, r, s' is the correct answer.
