In the article dumped what is the best definition for the word collaborator ?

a)  People who work together toward a common goal.

Explanation:

In the article "Dumped" by Helen Fisher, she writes about the pain that comes with a broken heart. The biological anthropologist studies love and how it affects those involved.

In her article, she mentioned that love is "an evolutionary adaptation" which also has its downside. And once this love turns the opposite way, the pain and suffering it brings the darker side of human love. In her experimental technique using "functional MRI", she along with other collaborators worked on determining how a brain in love acts. Here, the use of the word "collaborator" means other people who work alongside her to get the same goal, all having the same objective.
