b. Color of
c. Size of
d. Manufacturer of

Answer 1

The braking distance on a slippery road is mainly affected by the kind of contact the tires make with the road, rather than factors like tire color or manufacturer. The tread design, material, and tire condition are what contribute to effective braking.

Step-by-step explanation:

When the road surface is slippery, the braking distance is primarily dependent upon the kind of contact made by the vehicle's tires with the road surface. This contact is influenced by the tread design, the tire material, and the tire's condition (e.g., wear and inflation). A proper grip on the road is critical for effective braking; therefore, attributes like the tire's color or the manufacturer are irrelevant in this context. It is the interaction between the tire and the road that determines how quickly a vehicle can come to a stop under slippery conditions.
