The correct answer is C. Asking herself what she understands
Step-by-step explanation:
In reading, monitoring comprehension is a technique used to check understanding while reading, in this technique the reader takes short pauses every few lines or paragraphs and try to verify the content she/he has understood and if there is any information that it is not clear. This technique guarantees efficient reading as by it the reader can identify issues in understanding and solve them before trying to understand new information. Additionally, the point of monitoring comprehension is to check understanding rather than the number of pages read or the favorite section. Thus, if Juna is monitoring her comprehension she is asking herself what she understands.
