According to the equation v = √(T/μ), where T is tension and μ is linear density, wave speed is directly proportional to the square root of tension. Therefore, as tension increases, wave speed should also increase, but not necessarily linearly. Choice B best represents this relationship, where the curve is increasing but with a decreasing slope as tension increases.
