In a certain code language:
“Sun rises in the East” is coded as “ST SR SI SH SS”.
“Sun sets in the West” is coded as “ST SE SI SH SU”.
“Your house faces East” is coded as “SN SM SA SS”.
“His house faces West” is coded as “SC SM SA SU”.

Correct answer: C
Concept
In sentence-based coding, each word is assumed to have one fixed code, and the order of codes need not match the word order. A word shared by two statements must therefore correspond to a code shared by their code sets.
Comparing two statements that have only one targeted word in common isolates that word’s code; repeating the comparison independently checks the mapping.
Application
The first and third statements share only the word “East”. Their code sets share only SS, so East maps to SS.
The second and fourth statements share only the word “West”. Their code sets share only SU, so West maps to SU.
Cross-check
SS occurs in both statements containing East and not in either statement containing West; SU shows the reverse pattern. Thus the two mappings are independently consistent.
Result
Therefore, “East” and “West” are coded as SS and SU, respectively.
