Answer:
Option A.
Step-by-step explanation:
It is given that a sponsored link was delivered 100 times and 10 people clicked on it.
Number of impressions = 100
Number of clicks = 10
The formula for click-through-rate (CTR) is
[tex]CTC=\dfrac{\text{Total measured clicks}}{\text{Total measured impression}}\times 100[/tex]
[tex]CTC=\dfrac{10}{100}\times 100[/tex]
[tex]CTC=10[/tex]
The click-through-rate (CTR) would be 10%. Therefore, the correct option is A.
