App rejected due ipad image unsupported

So my app was rejected in review and the review stated this :

  1. The 13-inch iPad screenshots show an iPhone image that has been modified or stretched to appear to be an iPad image. Screenshots should highlight the app's core concept to help users understand the app’s functionality and value.

I don't want my app to be supported on ipad, as it probably won't look that good on it. So is there any way i could restrict that to iphones only?

Also the review said that

  1. We have started our review, but we need additional information to continue. Specifically, it appears your app may access or include paid digital content or services, and we want to understand your business model before completing our review.

And they have asked some 5 questions regarding the same.

Now, My application is completely free , yet they are saying that may include paid content. So where can i turn this off? In the pricing section , I have selected 0 in my local currency.

Thank you for your post. We believe we have resolved this issue. If you continue to experience issues during review, please contact us.
