Explanation:

Passing marks in option 1 is easily understood to mean favourable marks or sufficient marks in an exam.
Option 2 is incorrect as, here the word needs to be followed by a preposition (by). It should be, ‘…everybody passing by her on the road’ or simply, ‘passing on the road’.
Option 3 is correct. Passing the parcel is the name of a game.
In option 4, ‘passing car’ is correctly used to mean, ‘a car going past or moving by’.
Hence, the correct answer is option 2.
