Answer: C) Only the 114.3 cm shelf

Toloerance Levels are between 114.4 and 115.6 and 114.3 is the only one not in the tolerance levels.

Answer: B) Both the 114.3 and 115.7 cm shelves.

It is B because you can't have 114.3 because the lowest is 115 and the highest is 115.7 the highest it can be is 115.6.
