Topic: Embedded Question,

Best Answer Explained in Below-:

The question asks for an adjective that does not have a comparative degree form. Comparative adjectives are typically used to compare differences between two objects, and they often end in "-er" or are preceded by "more."

Let’s examine the options:

A) **Good** – The comparative form is “better.”
B) **Happy** – The comparative form is “happier.”
C) **Top** – This adjective indicates the highest position or rank but does not have a comparative form like “topper” or “more top.” It is a unique case, as it describes a status rather than a degree of comparison.
D) **Little** – Its comparative form is “less” when referring to size or quantity, or “littler” in some informal contexts.

Among the options, “top” stands out because it conveys the idea of being at the highest point without a comparative form. Unlike conventional adjectives that denote varying degrees, “top” asserts a definitive position, making it the correct choice in this context. Thus, the answer is **C: top.**
