How did the company react to the advert based on the influx of calls?

The correct choice indicates that the company experienced a significant and unexpected surge in responses following the advert, highlighting a positive outcome from their marketing strategy. This suggests that the advert effectively captured the interest of potential customers, leading to a high volume of calls. It implies that the company's expectations were likely exceeded and that the advert successfully generated engagement, signaling a strong market response to their promotional efforts.

Considering the other choices, they present scenarios that do not align with the idea of an influx of calls. For instance, stating that the company was disappointed by a low response or received no calls at all contradicts the premise of a significant increase in communication. Similarly, the option regarding discontinuing the advert implies a negative reaction, which would not be reflective of a positive influx of inquiries. Thus, the correct choice reflects a context of success and active engagement following the advert's release.
