Explanation:

- Statement 1: Negligence in performance of duties can justify the suspension or supersession of a cooperative society's board.

- Statement 2: Acts prejudicial to the interests of the society or its members are also grounds for such action.

- Statement 3: Failure to conduct elections as per relevant laws is a common reason for intervention.

- Statement 4: If there is no government shareholding, loan, assistance, or guarantee, then the power to supersede does not normally apply. Statement 4, therefore, is not a ground.

- Option 4 (1, 2, and 3) is correct, as these three points are valid grounds.
