The correct answers are be released immediately, surrender his passport, and not leave the city limits.

The verb mandate requires the subjunctive mood in the that-clause. The subjunctive uses the bare infinitive (base form) of the verb for all subjects, including third-person singular (he/she/it).

• be released immediately: Correct passive subjunctive (be + past participle).

• surrender his passport: Correct active subjunctive (base form surrender, not surrenders).

• not leave the city limits: Correct negative subjunctive (not + base form).

Surrenders is the indicative mood, which is generally considered incorrect following mandated that in formal English. To be kept is an infinitive, which doesn't fit the grammatical structure of a that-clause.
