Answer:
Number 2 is the correct answer.
Step-by-step explanation:
An apostrophe is used when one person/thing owns or is a member of something.
In this case, Mrs. Svoboda is hosting the Google Meet. And, apostrophes always go after the person's name, and before the "s".
There can be a case where the apostrophe goes after the "s", which is shown in number 3. That is used when a multiple number of people are owning whatever that is mentioned in the passage.
However, in this case, Mrs. Svoboda is only one person.
Therefore, number 2 is the correct grammatical answer.
Hope this helped!
