What do you have to be aware of in this situation?

You answered correctly because both indicated points apply in this situation. First, the driver of the yellow car may not see you properly—this is a common risk, especially if their view is obstructed or if they are inattentive, so you must remain cautious and prepared for unexpected actions from that driver. Second, loose chippings on the road surface increase the risk of slipping or losing control, so you should reduce speed and increase following distance to maintain safety. The third option about yielding right of way to the red car does not apply here because, according to the traffic rules and the given situation, you do not have to give way to that vehicle. Understanding these factors helps you anticipate hazards and adapt your driving accordingly for safer road use.
