**Why the Correct Answer is Right**
The correct answer is actually not provided in the question, so I will assume a typical set of primary colours. Primary colours include red, yellow, and blue. These colours are fundamental and cannot be derived from other colours. They are used as the base colours in colour mixing and are essential in art, design, and colour theory.
**Why Each Wrong Option is Incorrect**
**Option A:**
* This option is not provided in the question, so I will assume it is an incorrect option. If it were a primary colour, it would not be the correct answer.
**Option B:**
* This option is not provided in the question, so I will assume it is an incorrect option. If it were a primary colour, it would not be the correct answer.
**Option C:**
* This option is not provided in the question, so I will assume it is an incorrect option. If it were a primary colour, it would not be the correct answer.
**Clinical Pearl / High-Yield Fact**
In colour theory, primary colours are typically considered to be red, yellow, and blue. These colours are fundamental and cannot be derived from other colours. They are used as the base colours in colour mixing and are essential in art, design, and colour theory.
**Correct Answer:**
* This option is not provided in the question, so I will assume a typical set of primary colours.
