The correct answer is C. They are made of hard rubber and foam.<br /><br />Jounce bumpers, also known as fender bumpers, are designed to protect the vehicle from sudden impacts, such as when hitting a curb or another vehicle. They are typically made of a flexible material, such as polyurethane or polypropylene, which allows them to absorb the impact and prevent damage to the vehicle's paint and bodywork.<br /><br />Option A is correct because jounce bumpers do protect the vehicle from sudden impacts. Option B is also correct because jounce bumpers can help protect the vehicle while carrying heavy loads, as they can absorb the additional weight and prevent it from causing damage to the vehicle.<br /><br />Option D is incorrect because it states are correct, but option C is also incorrect. Jounce bumpers are not made of hard rubber and foam, but rather a flexible material that can absorb impact.
