The correct answer is C. I blinked and tried refocusing my eyes, and when I looked through my binoculars I really started to freak out about the sitch we were in
Explanation:
In informational writing, the purpose is just to inform the reader about a situation, issue or topic. Moreover, in a formal informational text, it is recommended to avoid the use of "I", colloquial terms and non-grammatical elements. In this context, the option "I blinked and tried..." is inappropriate because it includes the use of the pronoun "I" that is not recommended in formal texts; besides this, terms such as "freak out" and "sitch" are too informal and therefore inadequate.
