witnessed

The correct answer is witnessed.

The sentence is about the East Room, a venue that has seen many important events in the India-U.S. relationship. The word "witnessed" is the most appropriate word to fill in the blank because it means to see or experience something happen. The East Room has witnessed many important events, and the eminent Indian Americans who attended the reception were able to witness one of these events firsthand.

The other options are not as appropriate:

• Surpassed means to go beyond or exceed something. This does not make sense in the context of the sentence.
• Rebuffed means to reject or refuse something. This does not make sense in the context of the sentence.
• Grounded means to have a firm foundation or basis. This does not make sense in the context of the sentence.
