If in a coding system, SHELVES is coded as 1919515222219, and NOMINEE is coded as
1412131814225, then how will SEIZURE be coded in the same coding system?

Given, 

S H E L V E S : 19 19 5 15 22 22 19

Alternate alphabets are coded as per their place value and remaining alternate are coded as reverse

i.e; S, E, V, S are coded as per their place in English alphabets. 

; H, L, E remaining alternate alphabet are coded as reverse place value. 

Similarly, 

N O M I N E E : 14 12 13 18 14 22 5

In the same way, 

S E I Z U R E will be coded as 19 22 9 1 21 9 5 

Hence, Option C is correct.
