**Core Concept**
Parrot-like repetitive speech, also known as echolalia, is a symptom often observed in various neurological and psychiatric disorders. It is characterized by the repetition of words or phrases spoken by others, often without comprehension of their meaning. Echolalia can be a manifestation of impaired cognitive function, particularly in disorders affecting the frontal lobe and language processing centers.

**Why the Correct Answer is Right**
Echolalia is commonly associated with disorders that affect language processing and cognitive function, such as schizophrenia, autism spectrum disorder, and frontotemporal dementia. In these conditions, the brain's ability to generate novel language and suppress repetitive responses is impaired. This leads to the characteristic parrot-like repetition of words or phrases. The underlying neuroanatomical structures involved in language processing, including Broca's area and Wernicke's area, are often affected in these disorders.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because echolalia is not typically associated with anxiety disorders, which more commonly present with symptoms such as excessive worry, fear, or avoidance behaviors.
* **Option B:** This option is incorrect because stuttering, although a speech disorder, is characterized by dysfluency and repetition of sounds or syllables, rather than the repetition of entire words or phrases.
* **Option C:** This option is incorrect because apraxia of speech, a disorder of speech articulation, is characterized by difficulty with speech planning and execution, rather than repetition of words or phrases.

**Clinical Pearl / High-Yield Fact**
Echolalia can be a useful clinical sign in differentiating between various psychiatric and neurological disorders. It is often accompanied by other symptoms such as poverty of speech, neologisms, and impaired social interaction.

**Correct Answer: C. Autism Spectrum Disorder**
