To calculate the percentage change in sales of e-books between Year 1 and Year 3, we need to use the formula:

Percentage change = ((Year 3 value - Year 1 value)/Year 1 value) x 100%

Substituting the values from the table, we get:

Percentage change = ((240 - 52)/52) x 100%
Percentage change = 3.615 x 100%
Percentage change = 361.5% (rounded to one decimal place)

Therefore, the percentage change in sales of e-books between Year 1 and Year 3 is 360.9%, which corresponds to choice C.
