This question asks us to decode a word based on a given coding rule. We are provided with two examples of words and their corresponding codes. We need to figure out the logic behind the coding and then apply it to a new word.

Analyzing the Coding Rule for Word Puzzles

Let's look at the first example:

• Original Word: BEHOLD
• Coded Word: BDEHLO

Let's list the letters in the original word 'BEHOLD': B, E, H, O, L, D.

Now, let's examine the letters in the coded word 'BDEHLO': B, D, E, H, L, O.

If we arrange the letters of 'BEHOLD' alphabetically, we get: B, D, E, H, L, O. This exactly matches the coded word. It seems the rule is to arrange the letters of the original word in alphabetical order.

Let's verify this rule with the second example:

• Original Word: INDEED
• Coded Word: DDEEIN

The letters in 'INDEED' are: I, N, D, E, E, D.

Let's arrange these letters alphabetically: D, D, E, E, I, N. This matches the coded word 'DDEEIN'.

The rule is confirmed: the code for a word is formed by arranging its letters in alphabetical order.

Applying the Alphabetical Arrangement Rule to 'COURSE'

Now, we need to apply this rule to the word 'COURSE'.

The letters in 'COURSE' are: C, O, U, R, S, E.

Let's arrange these letters in alphabetical order:

1. C
2. E
3. O
4. R
5. S
6. U

Arranging the letters C, O, U, R, S, E alphabetically gives us CEORSU.

So, the coded word for 'COURSE' should be CEORSU.

Checking Options for the Coded Word

Let's compare our derived coded word 'CEORSU' with the given options:

• Option 1: CEROSU (Incorrect)
• Option 2: CEORUS (Incorrect)
• Option 3: CEOSUR (Incorrect)
• Option 4: CEORSU (Correct)

Our result, CEORSU, matches Option 4.

Therefore, in this code language, 'COURSE' is written as 'CEORSU'.

Additional Information: Types of Coding-Decoding

Coding-decoding questions test your ability to identify a pattern or rule in how words, letters, or numbers are transformed and apply that rule to a new input. Common types of coding include:

• Letter Shifting: Each letter is shifted a certain number of positions forward or backward in the alphabet (e.g., A becomes B, B becomes C, or A becomes Z, etc.).
• Reverse Ordering: The letters of the word are written in reverse order.
• Jumbling/Rearrangement: The letters within the word are rearranged according to a specific pattern (like the alphabetical order in this question, or reversing halves of the word, etc.).
• Substitution: Each letter is replaced by another specific letter or symbol.
• Number/Symbol Coding: Words are coded using numbers or symbols based on letter position, value, or a specific rule.

To solve coding-decoding problems, always look for the pattern in the examples provided. Compare the original word with the coded word letter by letter, consider their positions, alphabetical order, and frequency.
