Final answer:
The Piper PA-28 Cherokee (Archer and Arrow) has a constant slope from the top of the fuselage to the base of the vertical stabilizer.
Step-by-step explanation:
The subject of this question is physics, specifically related to aircraft design and aerodynamics.
The Piper PA-28 Cherokee (Archer and Arrow) aircraft has a much more curvy fuselage compared to the Cirrus SR20. The fuselage of the PA-28 has a constant slope from the top to the base of the vertical stabilizer, resulting in a smooth and gradual transition. It does not have a sudden drop from the top to the base of the vertical stabilizer. Therefore, the answer is option (b): Has a constant slope from top of fuselage to base of vertical stabilizer.
