Task: Answer the multiple choice question.
Query: Which drug exhibits a -3.540\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. CCOC(=O)N1CCN(C(=O)COC(=O)CSc2cc(C)c(Br)cc2C)CC1
b. CCN(CC)S(=O)(=O)c1ccc(Cl)c(NC(=O)CSc2cccc[n+]2[O-])c1
c. Oc1ccc(/C=N/NC(=S)N2CCOCC2)cc1
d. COc1cccc(/C=C/c2nc(C#N)c(NCC(C)C)o2)c1
e. CCOC(=O)c1c(S(=O)(=O)NC2CCN(C(=O)OCC)CC2)c(C)n(C)c1C
Answer: a. CCOC(=O)N1CCN(C(=O)COC(=O)CSc2cc(C)c(Br)cc2C)CC1
