Final answer:
The recommended width for a main kitchen aisle is 3 feet, which allows for easy movement and appliance use, while 4 feet may be favored if the kitchen is frequently used by multiple cooks or has heavy foot traffic.
Step-by-step explanation:
The question is concerned with the recommended width for a main kitchen aisle. The preferred width for functionality and safety in kitchen design is often referenced in guidelines related to home construction and renovation. When we consider the necessity for movement and the use of appliances within a kitchen, adequate space for traffic flow is vital. If we look at the options given and compare them to a line of one foot to a line of eight feet, we can infer the most suitable width for a kitchen aisle.
It is recommended that a main kitchen aisle should not be less than 3 feet wide to allow easy movement and space for appliance doors to open. If multiple cooks will be using the kitchen simultaneously, or if there is a flow of foot traffic through the kitchen, a width of 4 feet may be more suitable.
In light of this, the correct answer is: b) 3 feet, which provides enough space for a single cook and occasional foot traffic, with additional width considered based on specific kitchen needs or user preferences.
