Why each option

To represent a many-to-many relationship where one applicant can apply for multiple jobs and one job can have multiple applicants, a junction object should be implemented.

AMaster-detail field from Applicant to Job

A master-detail field would imply a one-to-many relationship, which contradicts the requirement for both 'many jobs' and 'many applicants'.

BFormula field on Applicant that references Job

A formula field is used for calculating or displaying data, not for establishing record-to-record relationships.

CJunction object between Applicant and JobCorrect

A junction object is necessary to represent a many-to-many relationship between Applicant and Job, allowing each applicant to relate to multiple jobs and each job to relate to multiple applicants.

DLookup field from Applicant to Job

A lookup field creates a one-to-many relationship, allowing an Applicant to be linked to only one Job, or a Job to have many Applicants, but not both in a many-to-many context.
