Final answer:
The correct answer is (D) There are no stairs in a one-story house, as the house described in the puzzle only has one story and therefore would not have and need for a second level or stairs.
Step-by-step explanation:
The question posed is a logic puzzle that is designed to test the student's attention to detail rather than their color vision knowledge. It states that a yellow one-story house has three rooms, and all the rooms including the furniture and TV are yellow. The question then asks about the color of the stairs.
The correct answer to the question is (D) There are no stairs in a one-story house. Since the house is described as a one-story house, it would not have a second level, and therefore, there would be no stairs present.
