Answer: Option B
The given code language is based on a simple substitution cipher, where each letter of the original word is replaced by a corresponding letter from the alphabet in a fixed sequence.
Let's decode the word SINGER to understand the pattern of substitution used in the code.
S I N G E RA I B C E D
We can see that the first letter S is replaced by A, which is the 19th letter of the alphabet, i.e., it is obtained by adding 18 to the position of S in the alphabet. Similarly, the second letter I is replaced by I itself, the third letter N is replaced by B, obtained by adding 1 to the position of N in the alphabet, and so on.
Using the same pattern of substitution, we can decode the word GINGER as follows:
G I N G E RC I B C E D
Hence, the code for GINGER in the given code language is CIBCED. Therefore, the answer is option B, CIBCED.
Some relevant definitions and formulas used in the solution are:

• Substitution cipher: A type of encryption technique where each letter of the original message is replaced by another letter or symbol based on a fixed rule or pattern.
• Alphabet: A set of letters used in a language, usually arranged in a fixed order.
• Position of a letter: The ordinal number that represents the place of a letter in the alphabet, starting from 1 for A, 2 for B, and so on.
• Addition: A mathematical operation that combines two or more numbers to get a sum.
• Decoding: The process of converting an encoded or encrypted message back into its original form.
