The slope of inductive reactance versus frequency graph in inductive AC circuit is:

Explanation

Inductive Reactance (XL): In an AC circuit, inductive reactance is the opposition offered by an inductor to the change of current, calculated as XL = 2πfL, where f is the frequency and L is the inductance.Key Concept: The slope of the inductive reactance versus frequency graph is determined by the constant proportionality factor (2πL), making the relationship linear. Therefore, as frequency increases, inductive reactance increases linearly.Logic: Since the graph represents a linear relationship, the slope remains constant, indicating constant inductance, which is why Option A is correct. Options B and C are incorrect because they imply a change in inductance, which is constant. Option D is incorrect as it suggests no relationship, which is not true.
