In the following question, you'll find four other words provided alongside a given word. One of these words cannot be formed using the letters of the given word. Can you identify that word?
Given word: "MACHINES"

Let's analyze the letters available in the given word "MACHINES":
$$\text{M, A, C, H, I, N, E, S}$$

Now let's check each option against these available letters:

* (A) SEAM: Contains $\text{S, E, A, M}$. All these letters are present in "MACHINES". (Can be formed)
* (B) NAMES: Contains $\text{N, A, M, E, S}$. All these letters are present in "MACHINES". (Can be formed)
* (C) CAMEL: Contains $\text{C, A, M, E, L}$. The letter 'L' is not present anywhere in the word "MACHINES". (Cannot be formed)
* (D) MESH: Contains $\text{M, E, S, H}$. All these letters are present in "MACHINES". (Can be formed)

Therefore, "CAMEL" is the word that cannot be formed.
