A Relationship Between Skills and Employees Is Typically Modeled as M:N

A relationship between Skills and Employees is typically modeled as M:N in an REA database model since

A) one employee may possess many skills,and one skill may be possessed by more than one employee.
B) many employees possess skills,and many skills are possessed by employees.
C) employees can be trained to learn all skills,and all skills are possessed by at least one employee.
D) The relationship would be 1:N not M:N,because most employees are hired for a specific job that requires a specific skill,even though a specific job could be done by many employees.
