    B 36000 Correct Answer Incorrect Answer
    C 34320 Correct Answer Incorrect Answer
    D 38400 Correct Answer Incorrect Answer
    E 40320 Correct Answer Incorrect Answer

    Solution

    Total number of arrangements = 8! = 40320 ways
    If we consider 3 team dancers as one unit, number of arrangements among themselves = 3! = 6 ways
    Number of arrangements of remaining 6 performers = 6! = 720 ways
    Therefore, required number of ways = 40320 тАУ (6 ├Ч 720) = 36000 ways
