The car ran . . . . . . . . the railings.

The correct answer is D. into.

The car ran into the railings. This means that the car hit the railings head-on. The other options are not correct because they do not accurately describe the action of the car.

• Option A, to, is incorrect because it suggests that the car was moving towards the railings but did not hit them.
• Option B, in, is incorrect because it suggests that the car was inside the railings.
• Option C, at, is incorrect because it suggests that the car was close to the railings but did not hit them.

The word “into” is used to describe the action of a moving object hitting or colliding with another object. In this case, the car is the moving object and the railings are the object that it hits.
