Choose the correct word to complete the eccentric billionaire's last will and testament.

"I stipulate that my beloved pet penguin, Sir Waddles, _____ fed only the finest imported caviar every morning."

The correct answer is be.

Formal verbs of commanding or stipulating (like "stipulate", "demand", or "order") require the base form of the verb in the that-clause. For the verb "to be", the base form is simply "be", even for third-person singular subjects like "Sir Waddles".
