Option 1 (It describes the days being discussed) is correct since it refers to a particular set of days, those in which the subject of the sentence goes jogging, and a particular moment of the day which is the morning.
Option 3 (It creates a compound-complex sentence) is correct because the sentence contains two independent clauses and a dependent clause.
The two independent clauses are: "<em>My mind seems to process ideas faster</em>" and "<em>My mood is more positive</em>". These two independent clauses are joined by the coordinating conjunction "<em>and</em>". The compound-complex sentence also includes a dependent clause "<em>On days when I go jogging in the morning</em>" which is dependent on the two main independent clauses previously mentioned.
point of view is how one individual sees an event, different points of view can see different angles of events. Point of view can also apply to any bias's an individual may have.
