A convex mirror is used as a rear view mirror in cars because it gives a wider field of view and produces an upright image that is smaller, making it ideal for seeing more behind the vehicle.

- (C) Plain mirror: A plain mirror would not provide the necessary field of view.
- (D) None of these: This is incorrect.

Step 3: Conclusion.
Thus, the correct answer is (B) Convex mirror.
