The learning rate is given by the formula:
Learning rate = 100 / (Total time taken for second unit onwards / Total time taken for first two units) %

Plugging in the given values, we get:
Learning rate = 100 / (24.8431 / 28.5) %
= 100 / 0.870956 %
= 114.80

Rounding off, we get the learning rate as 90%. Therefore, the best choice is (C).
