Explanation:

Among the given options, 'द्वारका' (Dwaraka) is the correct spelling. The common mistake is to write 'द्वारिका' (Dwarika), but 'द्वारका' is the grammatically correct form. 'ज्योत्सना' should be 'ज्योत्स्ना', 'मंत्रीमंडल' should be 'मंत्रिमंडल', and 'हरितिमा' is not a standard correct word (should be 'हरितमा' or 'हरियाली').
