Final answer:
To complete the sentence, use the present continuous form 'calling' because the action is happening now, resulting in the sentence 'Jasmine is calling her friends at the moment.'
Step-by-step explanation:
To complete the sentence using the present or present continuous form of the verb 'call', you need to look at the context provided by the sentence to determine which tense is appropriate. The sentence 'Jasmine is ______________________ her friends at the moment.' indicates an action that is taking place right now, which signals the use of the present continuous tense.
The correct way to complete the sentence is: Jasmine is calling her friends at the moment. The word 'calling' is the present continuous form of the verb 'to call', fitting perfectly in this context where the action is in progress.
