D.The patch doubles in size every day, so on the 47th day the patch will be half the size it is on the 48th day.
Hint: It's a 25-word phrase with 80 letters, starting with "T".
Answer
The patch doubles in size every day, so on the 47th day the patch will be half the size it is on the 48th day.
Why this is the answer
Since the patch's size doubles every single day, it must have covered exactly half the lake just one day before it covered the whole lake - day 47.
