Your Answer is

Correct Answer is H

Explanation

Because the coefficient of the quadratic term of the equation is determined to be 1, this equation must be a quadratic equation of one variable. If there is only one solution, there can only be two identical solutions when delta=0. Therefore, k⁴-8k=0 can be obtained and k=0 (according to the question, discard) or k=2. Therefore, H.
