Answer:
The answer is A.7
Explanation:
(Dead cells are in black) (Infected are potato color with green inside them) (Healthy cells are potato color without green)
First, 13 is wrong because there are not yet 13 dead cells
Second, 20 is wrong because there are no 20 dead cells
Third, 29 is wrong because there are no 29 dead cells
So 7 is the only answer and it is correct
Hope this helps
