Answer:
list B
Step-by-step explanation:
Given that there are two clicks , list A and B.
List A has a click rate of 5% and payment 0.25 dollars
Hence click rate of 1% costs = 0.25/5 = 0.05 dollars
Similarly for list B,
For a click of 10% payment done = 0.35$
Hence for one click payment = 0.35/10 = 0.035
Since both rates have been converted to rate for unit click we can compare both.
List A = 0.05 and List B= 0.035
List A unit click rate > that of list B
Hence list B has the lower cost per click.
