Given the signage, I must moderate my speed, and:

AUse the engine as a brake aid.Correct
BOnly use the service brake because the descent is dangerous.
CStop before the descent, which is at a distance of 200 meters.
Explanation
Given the dangerous descent sign, the driver must moderate their speed and use an appropriate gear ratio so that the engine acts as a brake aid. This procedure helps to safely control the vehicle's speed, preventing excessive wear and overheating of the brakes. The other options are incorrect because using only the service brake on a steep descent can cause a loss of brake effectiveness due to overheating. Furthermore, the danger sign does not impose any obligation to stop before the start of the descent.
