Explanation

For answer  A  and  B 

If the headlights are on before starting the engine and their intensity decreases gradually, this is a clear sign that the battery is discharged. In the absence of the alternator supplying additional current, the battery is the only source of energy, and a weakened battery cannot maintain the necessary voltage. Also, if when pressing the horn the sound emitted is weak and interrupted, this indicates that the battery can no longer supply enough energy to power the electrical system.


For answer  C 

The discharge of the battery does not affect its weight, which remains unchanged regardless of the level of charge.


The correct answer is: A and B
