Charitable Org Worksheet and Donor Advised Funds

I created a Schwab Donor Advised Fund.  I'm using the Charitable Org Worksheet to list the $ I transferred to the DAF in 2021.  Question 4 at bottom of the Worksheet asks "What Type of charitable organization was it? What box do I check? (what's a "50% charity"?)

> 50% charity

> Other than 50% charity

> 50% Charity, 100% Donation
