The verb form that is used to indicate present perfect tense is have + verb - ed.
For example:
I <u>have painted </u>a beautiful painting. 
        
                    
             
        
        
        
Chronological............................................................
        
                    
             
        
        
        
I’m sorry but without the text I can’t answer the question I don’t know what info is there so I can’t answer without a risk
        
             
        
        
        
A coma will separate her actions, so B is correct. Hope this helps :)
