Conditions:
(i) If the first element is a symbol and the last element is a number, the codes for these two (the first and the last elements) are to be interchanged.
(ii) If the first element is an odd number and the last element is an even number, the first and last elements are to be coded as ©.
(iii) If both the second and third elements are perfect squares, the third element is to be coded as the code for the second element.
Ψ62%85

Given: Ψ62%85

Conditions:
i) If the first element is a symbol and the last element is a number, the codes for these two (the first and the last elements) are to be interchanged. (Follow)

ii) If the first element is an odd number and the last element is an even number, the first and last elements are to be coded as . (Does not follow)
iii) If both the second and third elements are perfect squares, the third element is to be coded as the code for the second element. (Does not follow)​

now Ψ62%85 $$\rightarrow$$​​

Ψ $$\rightarrow$$S, 6 $$\rightarrow$$ N, 2 $$\rightarrow$$ M, % $$\rightarrow$$R, 8 $$\rightarrow$$K, 5 $$\rightarrow$$​T

Then the next word will be; SNMRKT

Thus, the correct answer is (a) SNMRKT.
