Answer 2

a. has been cooking

The correct option is "a. has been cooking." This is because the sentence is in the present perfect continuous tense, which is used to talk about actions that started in the past and are still continuing in the present. In this case, Ann has been cooking for a period of time that started in the morning and is still ongoing. Therefore, the present perfect continuous tense is the most appropriate choice.
