Final answer:
The proper way to hold a steering wheel for safe driving is at the 9 and 3 o'clock positions. This positioning offers both control over the vehicle and safety in the event of an airbag deployment, making option b. 3 and 9 the correct choice.
Step-by-step explanation:
The question involves the correct hand positioning on a steering wheel for safe driving. The recommended and safest positions on the steering wheel have historically been at the 9 and 3 o'clock positions, similar to those on the face of a clock. This recommendation is primarily due to the advent of airbags in steering wheels, which could cause injury if hands are placed in the previously recommended 10 and 2 positions.
When considering the proper way to hold a steering wheel, experts suggest imagining the steering wheel as the face of a clock. Placing one hand where the 9 would be and the other hand where the 3 would be is considered the optimal grip. This placement allows for both maximum control over the vehicle and minimum risk of injury if an airbag were deployed. Therefore, the correct option for the question is b. 3 and 9.
