The correct answer is option two.
Subjective means that something is positioned or determined by personal feelings, preferences or opinion. As a consequence, the expression that refers to small creatures as "pretty" is subjective because it is based on the narrator or author's personal judgement. Prettiness cannot be observed by an objective perspective because it always depends on the individual perception of the viewer.
The rest of the statements are indeed objective since they are based on hard facts and real evidence.
