• A. 1:8
• B. 1:12
• C. 1:3
• D. 1:20

Hint:

A slope of 1:12 is the standard for wheelchair ramps to ensure safe access for people with mobility impairments.

Answer 1

The Correct Option is B

Step 1: Understanding the wheelchair ramp.
A wheelchair ramp is designed to provide access to people using wheelchairs, and the slope needs to be gentle for safety and comfort.
Step 2: Explanation.
According to accessibility standards, the maximum acceptable slope for a wheelchair ramp is 1:12. This means for every 1 unit of vertical rise, the ramp should extend 12 units horizontally.
Step 3: Conclusion.
Thus, the maximum acceptable slope ratio is 1:12.
