**Question:** All of the following are fluent aphasia's except-

A. Broca's aphasia
B. Wernicke's aphasia
C. Congenital aphasia
D. Agrammatism

**Core Concept:**
Fluent aphasia is a type of language disorder characterized by preserved fluency of speech but with impaired comprehension and expression. There are two main types of fluent aphasia: Broca's aphasia and Wernicke's aphasia. Congenital aphasia refers to language impairments present from birth due to genetic or developmental factors, while agrammatism is a specific type of language disorder characterized by difficulties with grammar and sentence structure.

**Why the Correct Answer is Right:**
Congenital aphasia is incorrect because it refers to language impairments present from birth due to genetic or developmental factors. Agrammatism is also incorrect as it is a specific type of language disorder characterized by difficulties with grammar and sentence structure.

**Why Each Wrong Option is Incorrect:**
A. Broca's aphasia is a type of fluent aphasia characterized by speech output difficulties, but preserved comprehension.
B. Wernicke's aphasia is a type of fluent aphasia characterized by preserved speech output but impaired comprehension.
D. Agrammatism is a specific type of language disorder characterized by difficulties with grammar and sentence structure.

**Why D is Incorrect:**
Agrammatism is a specific type of language disorder characterized by difficulties with grammar and sentence structure. While agrammatism is related to language impairments, it is not an aphasia itself but rather a feature within aphasia spectrum.

**Core Concept:**
Aphasias are a group of language impairments resulting from damage to specific brain regions. They are classified into Broca's aphasia, Wernicke's aphasia, and transcortical motor aphasia.

**Why B is Incorrect:**
Wernicke's aphasia is a type of fluent aphasia characterized by preserved speech output but impaired comprehension. This means that a person with Wernicke's aphasia can speak fluently but has difficulty understanding spoken or written language.

**Why A is Incorrect:**
Broca's aphasia, on the other hand, is characterized by speech production difficulties and intact comprehension. This means that a person with Broca's aphasia may speak with a non-fluent, broken speech output but can understand spoken or written language well.

**Why C is Incorrect:**
Congenital aphasia refers to language impairments present from birth due to genetic or developmental factors. It does not specifically refer to any type of aphasia, but rather describes a broader category of language impairments.

**Why D is Correct:**
Agrammatism, being a specific feature within the aphasia spectrum, is characterized by difficulties with grammar and sentence structure. Although agrammatism can be present in some forms of aphasia, it is
