The word "errand" means a short journey undertaken to do something for someone else. In the context of the sentence, "Dr Rajnish has employed an errand boy for his office works", Dr Rajnish has employed a boy to run errands for him in his office. The other options are not as appropriate.

• Errant means straying from the right path or behaving in a way that is not considered acceptable. This does not make sense in the context of the sentence, as Dr Rajnish is not employing a boy who is straying from the right path or behaving in a way that is not considered acceptable.
• Arrogance means a feeling of superiority over others. This does not make sense in the context of the sentence, as Dr Rajnish is not employing a boy who is arrogant.
