For the quadratic function to have no real zeroes, the discriminant must be less than zero: .

It is also given that . We need to analyze the implications of this inequality.

Since and the quadratic function has no real zeroes, the graph of the function does not cross the -axis. This means that the function is either entirely above the -axis or entirely below the -axis.

Given that , the function must be entirely below the x -axis for all values of . This implies that must be less than zero to satisfy the inequality when and are constants.

Therefore, the correct answer is .
