Final Answer:
Characterized by an itchy scalp and small skills usually attached in masses to the scalp or scattered loose in the hair, characteristic features include an itchy scalp and small scales, often attached in masses or scattered loosely in the hair.
So, the correct option is c.
Step-by-step explanation:
When deciding the best descriptive statement for a condition characterized by an itchy scalp and small scales, the objective is to communicate the two main symptoms clearly and also their possible presentations (attached in masses to the scalp or scattered loosely in the hair). Let's evaluate each option provided:
a) "The itchy scalp and small scales characterize the condition, often attached in masses to the scalp or scattered loosely in the hair."
This sentence correctly identifies the two main characteristics of the condition. However, the structure of the sentence could potentially be misread to suggest that the itchy scalp is what is attached in masses, rather than the small scales. While the meaning is understandable, the phrasing could be more precise.
b) "Small scales, attached in masses or scattered, characterize the condition with an itchy scalp."
This option begins with the small scales and describes their presentation before mentioning the itchy scalp. The sentence structure implies that the small scales are the primary feature and the itchy scalp is an additional characteristic. The phrasing is clear, but it could imply a hierarchy in symptoms that may not be intended.
c) "Characteristic features include an itchy scalp and small scales, often attached in masses or scattered loosely in the hair."
This choice provides a balanced presentation of the two main features. It clearly states that both an itchy scalp and small scales are characteristic, and it accurately describes the possible presentations of the scales. The use of "include" implies that these are not necessarily the only characteristics but emphasizes them as key features.
d) "An itchy scalp and small scales, whether attached in masses or scattered loosely in the hair, are characteristics of this condition."
This sentence also accurately conveys the characteristics of the condition, with an emphasis on the symptom of an itchy scalp followed by a description of the small scales. The phrase "whether attached in masses or scattered loosely" effectively clarifies the possible presentations of the scales.
In choosing the best description, clarity and accuracy are paramount. Option c) is effective because it is clear and concise, gives equal weight to the itchy scalp and small scales, and describes the presentation of the scales without suggesting an inappropriate hierarchy of symptoms or possible misinterpretation.
Therefore, c) is the most effective way to describe the condition, providing an equal balance and clear characterization of both symptoms.
