Write answer in between .Q:A medical student is reviewing dose-response curves of various experimental drugs. She is specifically interested in the different factors that cause the curve to shift in different directions. From her study, she plots the following graph see image. She marks the blue curve for drug A, which acts optimally on a receptor. After drawing the second green curve, she discovers that this drug B has a lower ability to produce a reaction than the first one. She also discovers that more of the second drug B is required to produce the same response as the first one. Which of the following terms best describes the activity of drug B in comparison to drug A?? A: Lower potency, B: Higher efficacy, C: Higher potency, D: Increased affinity, E: Decreased efficacy,  <response>: This is a question about analyzing dose-response curves for two drugs, A and B. The key details are:- Drug A acts optimally on a receptor and is represented by the blue curve. - Drug B has a lower ability to produce a reaction than drug A and is represented by the green curve. - More of drug B is required to produce the same response as drug A.Based on these details, drug B has lower potency compared to drug A. Potency refers to the amount of drug required to produce a given effect. Since more of drug B is needed to get the same response as drug A, drug B has lower potency.A: Lower potency
