Which popular dance is believed to have been passed by Krishna to his gopikas and is performed on nine consecutive nights?

Garba is the correct answer - it is a traditional Gujarati folk dance performed during Navratri (nine nights) and is traditionally associated with Krishna and the gopikas of Vrindavan. Dandiya is also performed during Navratri but typically involves sticks and pairs, not attributed to Krishna's direct传承. Bhangra is a Punjabi harvest dance, while Kaikottikali is a Kerala women's dance.
