To find the learning rate, we need to calculate the percentage decrease in time taken to complete each subsequent unit. 
For the first and third unit, the percentage decrease is: 
[(time taken for first unit - time taken for third unit) / time taken for first unit] x 100% 
= [(15 - 14) / 15] x 100% 
= 6.67% 
This means that the learning rate is between 95% and 97%, which corresponds to answer B.
