**Core Concept**
The question is about identifying a type of atypical mycobacteria that produces pigment. Atypical mycobacteria, also known as non-tuberculous mycobacteria (NTM), are mycobacteria other than *Mycobacterium tuberculosis* that can cause disease in humans.

**Why the Correct Answer is Right**
The correct answer is related to the production of pigment, which is a characteristic feature of certain atypical mycobacteria. *Mycobacterium scrofulaceum* is one such example, known for producing pigment.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not specify a pigment-producing atypical mycobacteria.
**Option B:** Similarly, this option does not identify a known pigment-producing mycobacteria.
**Option C:** This option is also incorrect as it does not relate to a pigment-producing species.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that *Mycobacterium scrofulaceum*, a pigment-producing atypical mycobacteria, is often associated with cervical lymphadenitis in children.

**Correct Answer:** D. Mycobacterium scrofulaceum
