Imagine that you are an interior architecture/biology double-major. While at home during break, one of your friends asks you to design and help build a spiral staircase that is modeled after a DNA molecule

The stair case must have 12 steps, and each step needs to be 6-feet wide. You say, "OK, as long as you provide the materials." So, your friend asks you for a list of materials needed to build the staircase. Which of the following includes the items necessary to make a staircase that is based on the molecular structure of a DNA molecule?
A. 1 railing and 12 boards (each of which is 6- feet wide)
B. 2 railings and 12 boards (each of which is 6-feet wide)
C. 2 railings and 24 boards (12 that are 2-feet long and 12 that are 4-feet long)
D. 2 railings and 24 boards (each of which is 3-feet long)
E. 1 railing and 24 boards (12 that are 2-feet long and 12 that are 4-feet long)
F. 1 railing and 24 boards (each of which is 3- feet long)
