What to do with cracked iPhone and please get many option as you can

There are only two appropriate options:

1. Live with it
2. Schedule an appointment at your Apple Store Genius Bar or Apple Authorized Service Provider and pay to have the screen replaced on your iPhone
3. Here is a link which will help you should you decide to pay to have the screen replaced --> iPhone Screen Repair & Replacement - Official Apple Support

If you're expecting other options, you're going to be disappointed. Either get the screen replaced with an Authentic Apple Screen at an Apple Store or Apple Authorized Service Provider or live with it.
