What to do when UX survey respond rates are close to each other?

I've asked the following question:

"You've found an activity you like on our website. Which one of statements below would make you more likely to inquire about this activity."

  1. This activity is selling out fast!
  2. This activity is very popular!
  3. This activity is trending!

Results are pretty close: 43% 38% 35%

How to analyze this? How much difference do I need in order to pick a winning option?
