As per In App Purchases Guide in apple's developer resources, it clearly says that we can offer free trial option.
But I couldn't able to see it anywhere when I am setting in App purchases in iTunesConnect. Are they still offering that? Where can I find it?
Here is the screen shot of what I see in my iTunesConnect
In iTunes Connect you will find it here
App > Manage In App Purchases > Subscription Basic > 1 Month > Offer a free trial?
