jubilant

The correct answer is jubilant.

The sentence is about a crowd that is giving a warm welcome to their newly elected leader. The word "jubilant" means "feeling or expressing great happiness and triumph."

• Noisy means making or given to making a lot of noise. This does not make sense in the context of the sentence, because the crowd is not just making a lot of noise, they are expressing their happiness and excitement.
• Troublesome means causing difficulty or annoyance. This does not make sense in the context of the sentence, because the crowd is not causing any difficulty or annoyance, they are welcoming their newly elected leader.
• Melancholic means feeling sad or depressed. This does not make sense in the context of the sentence, because the crowd is not feeling sad or depressed, they are feeling happy and excited.
