Answer:
A.
Step-by-step explanation:
The correct word to complete the given sentence would be 'precise.'
The term precise is derived from the Latin word praecis which means 'cut short.' The word precise means something that is marked with accuracy and exactness.
The speaker in the given statement is asserting that he/she doesn't remember that exact moment when he/she heard about being accepted to the university, but remembers being excited upon hearing the news.
Therefore, option A is correct.
