Answer: B

Explanation:

To represent that an applicant has applied for a job when each applicant can apply to multiple jobs:

Option B: Junction object between Applicant and Job

A many-to-many relationship in Salesforce is modeled using a junction object. The junction object would have two master-detail relationships, one to Applicant and one to Job. Implementation:

Create a custom object, e.g., JobApplication.

Add master-detail relationships to both Applicant and Job.

Reference: "Use a junction object to model a many-to-many relationship between two objects."

Option A: A master-detail from Applicant to Job implies that each Applicant is associated with only one Job.

Option C: A formula field cannot represent a many-to-many relationship.

Option D: A lookup field from Applicant to Job represents a one-to-many relationship, not many-to-many.
