Correct Answer:
B. Enthusiasm
The correct synonym for ZEST is Enthusiasm. Zest refers to a feeling of great enthusiasm and energy, often accompanied by a keen enjoyment or excitement for something. Enthusiasm perfectly captures this meaning, denoting intense and eager enjoyment, interest, or approval. Conversely, Passive describes a lack of active response or resistance, directly opposing the energetic nature of zest. Disgust signifies a strong feeling of revulsion, which is entirely unrelated to zest. Various simply means diverse or different, bearing no semantic connection to the concept of spirited enjoyment.
