In a certain code the alphabets A, B, C, ... are given ranks 1, 2, 3, .... respectively, and then $$n^{th}$$ letter is coded as $$k^{th}$$ letter where $$1 \leq k \leq 26$$ and 5n = k(mod 26). For example, the $$12^{th}$$ letter L is coded as the $$8^{th}$$ letter H because 60 = 8 (mod 26). For decoding reverse process is followed. Based on this answer questions
TS ICET 2021 Shift-2 (19th Aug) - Question 58
The letters that are not changed under the given code are
