She began to babel in front of the guests.

The correct answer is A. The word “babel” means to talk or shout in a confused or unintelligible way. In this case, the woman is talking loudly and incoherently in front of the guests. This is likely because she is nervous or excited, or perhaps she is simply trying to get everyone’s attention.

The other options are incorrect for the following reasons:

• Option B, “din,” means a loud, confused noise. This is not the best answer because it does not capture the sense of the woman’s speech being unintelligible.
• Option C, “mourn,” means to express deep sorrow or regret. This is not the best answer because it does not capture the sense of the woman’s speech being loud or confused.
• Option D, “cry,” means to shed tears. This is not the best answer because it does not capture the sense of the woman’s speech being loud or confused.
