New In field - Really Need help on why some of the hands on challenges are not completing - Can anyone tell me my mistake in the below given hands on challenge.

Hi @rohita Ballabh joshi I am a member of Trailhead Help, I assume that this issue needs further review and we may need access to your Salesforce org where you are trying to complete the challenge. We will create a case on behalf of you for this issue and reach out to you via email to investigate further. Thank you!
