SEGMENT question from CJA practice exam

Hi,
this is for a CJA practice exam but given the similarity to Analytics, i ll drop it here anyway.

in the practice exam i received the following question:

"A report requires you to build an audience of web visitors that viewed the Checkout page, then afterward went to the Cart page in a single session. Which of the following filters will output the correct audience?"

these are the 3 options:

from the screenshot what would you choose? figure 1,2 or  3 in order from the top to the bottom, which one would you choose a why?

i chose one that i thought was correct but in the end it was not.
