The correct answer is A board is allowed to have more than one board administrator.

This is correct because boards in Jira can have multiple administrators who share responsibility for configuring the board settings and board-specific features such as columns, quick filters, and card layout. Board administrators manage the board level configuration and they can be added or removed independently of project roles.

A Jira project can have multiple project leads is incorrect because a Jira project has a single project lead field and that lead is one user who is designated as the project lead for ownership and default responsibility.

A saved search filter can be owned by several users is incorrect because saved filters have a single owner and can be shared with groups or projects but ownership remains with one user.

The default assignee for issues can be either the project lead or the component lead is incorrect because default assignee choices are configured at the project level and may be set to the project lead or to be unassigned, while component leads provide a default assignee for issues assigned to that component only. The statement as written implies both apply universally which is not accurate.

Project administrators can create new global roles and assign members to them is incorrect because creating and managing project roles and global role definitions is an administrative action reserved for Jira administrators rather than project administrators.
