The answer is: d. The practice by which the managers of a company show favoritism to their own relatives and close friends.

Explanation:

Nepotism is the exaggerated predilection that some active civil servants who hold public office have regarding their family, relatives and friends when making concessions or hiring state employees. In these cases, the individual who accesses a public job achieves the objective by its proximity and loyalty to the ruler or official in question, and not by his own merit or ability.

The answer is: d. The practice by which the managers of a company show favoritism to their own relatives and close friends.
