Answer:
The accurate answer is Option A
Explanation:
The controlling idea includes your viewpoint on the matter. It explains what course you are going to take in composing about the subject. It encourages the reader to know your intention for composing the paragraph.
It is not a selective line in the statement. Hence Option D is incorrect.
The completion of a paragraph concludes the paragraph by summing the opinions stated in it. Option C is therefore not the accurate answer.
Option B is also false because actually, the principal subject matter included in the statement carried on the controlling idea. The principal subject is in accordance with the course of the construction of the paragraph.
So, according to the description stated above, Option A is the correct answer.
