Explanation:
The selected answer option is **incorrect**, the correct formula for **Click-Through Rate (CTR)** is defined as the **number of clicks divided by the number of impressions, expressed as a percentage**. This metric measures how effective an ad is at prompting users to take action by clicking on it. It is calculated by dividing the total number of clicks an ad receives by the number of times the ad is shown (impressions), then multiplying by 100 to express it as a percentage. A higher CTR typically indicates that the ad is relevant and compelling to users, as more people are clicking on the ad relative to how often it is shown. This is an important metric for assessing the performance of ads, as it reflects user engagement with the ad content.
