The correct answer is: You can use a single choice custom field as the basis for the board estimations.

This statement is incorrect because company managed Scrum boards do not let you pick an arbitrary single choice custom field as the board estimation statistic. The board estimation setting accepts specific statistics such as Story points, Original estimate (time), or Issue count and it maps to the field Jira expects for that statistic. You cannot point the board at a generic single choice custom field and have Jira treat those values as the board estimation metric.

A burndown chart can plot remaining work using an estimation metric other than story points is not the right answer because it is a true statement. The burndown chart uses whatever estimation statistic the board is configured to use so it can show remaining work in story points or in time or in issue count depending on the board setting.

A team may estimate using story points while logging time on sub tasks in hours is not the right answer because it is also true. Estimation and time tracking are separate features so a team can estimate at the issue level with story points while tracking work logged on subtasks in hours or minutes without changing the story point estimates.

Only the board administrator and the project administrator for the board location can alter the Estimation Statistic setting is not the right answer because this describes who normally makes the change through board settings. Changing the estimation statistic is performed via the board configuration and requires board administrator permissions or project administration rights for the project where the board is located. Administrators with broader system privileges can also perform administrative actions, but the operational change is done from the board settings by those roles.
