Answer 1

Hmm... Interesting Question :-

$\color{red}{ANSWER :-}$

In The Active Voice *You Have Parked The car in the line* , Our Subject Is 'You' Which is plural in nature. Now since the Subject is Plural We use plural Verb Have.

While in The Passive Voice *The Car Has been Parked By You , Our Subject is 'Car' Which is Singular In nature. And Thus It has Singular verb Has.

Hope you Doubt is Clear
