Step 1: Understanding the Question:
The question asks to complete the sentence about the role of prose in literary appreciation, based on the central argument of the passage.
Step 2: Analyzing the Passage:
The passage repeatedly emphasizes the connection between language and the specific "thought content" it aims to convey. Key sentences include:
\[\begin{array}{rl} \bullet & \text{"our main concern is with the kind of language used to match the thought content..."} \\ \bullet & \text{"The nature of the thought-content will determine first the register of the language."} \\ \bullet & \text{"...language must convey, with a sense of economy, ease of expression and exactness of approach, the thought-content of the writer."} \\ \end{array}\]
These points directly support the idea that the language must be appropriate for the content. The passage warns against "bombastic words" (ruling out option B) and only mentions technical registers for technical ideas, not as a general rule (ruling out option D).
Step 3: Final Answer:
Based on the passage, prose for literary appreciation should use language appropriate to its content. Therefore, option (A) is the correct answer.
