is the right option.

Answer 2

Answer: 1. has called

Explanation:

The sentence is in present perfect tense.

The present perfect tense is used in a sentence where the work will be done in the present day but in future tense that means the work will be done in any time period of the present day. So, this sentence has present perfect tense.

In this sentence, the term “By the time” is used that means Cynthia will be booking within some time so within that time period she can also call her sister. So, she has to perform two jobs in a given time period.

Hence, the perfect word is “has called”.

Thus, the sentence will be “By the time Cynthia books the flight to Iceland, she has called her sister about the visit”.
