1. Correct Answer: D
 
 2. Explanation of the statements:
 
     ● Statement I is incorrect.  
           ○ Not all types of UAVs are capable of vertical landing.
           ○ Vertical landing is typically a feature of certain UAVs like quadcopters or VTOL (Vertical Take-Off and Landing) drones.
           ○ Fixed-wing UAVs, for example, usually require a runway or a catapult system for landing.
           ○ Therefore, the ability to perform vertical landing is not universal across all UAV types.
 
     ● Statement II is incorrect.  
           ○ Automated hovering is a feature primarily associated with multirotor UAVs, such as quadcopters.
           ○ Fixed-wing UAVs cannot hover as they rely on forward motion to generate lift.
           ○ Thus, not all UAVs can perform automated hovering, as it depends on the design and type of the UAV.
 
     ● Statement III is incorrect.  
           ○ UAVs can be powered by various sources, not just batteries.
           ○ Some UAVs use internal combustion engines, fuel cells, or solar power as their energy source.
           ○ The choice of power supply depends on the UAV's design, purpose, and operational requirements.
           ○ Therefore, it is incorrect to say that all UAVs use only batteries as a power source.
