The Six Sigma quality level can be calculated using the formula: 
Six Sigma level = (Tolerance range)/(6 * Process standard deviation) 
Substituting the given values, 
Six Sigma level = (10ó)/(6 * 1ó) = 1.67 
Since Six Sigma level is typically rounded down to the nearest whole number, the Six Sigma quality level would be 1. Therefore, the best choice is A.
