Task: Answer the multiple-choice question.
Query: Which drug exhibits a 0.486\% 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) COC(=O)c1ccc(/C=N/Nc2nc3ccccc3[nH]2)cc1
(b) O=C(NC(=S)Nc1cc([N+](=O)[O-])ccc1Cl)c1ccccc1
(c) O=C(NCC(c1cccnc1)N1CCN(c2ccc(F)cc2)CC1)c1ccc(F)cc1
(d) O=C(N/N=C/c1ccc(-c2ccc(Br)cc2)o1)c1ccc2c(c1)OCO2
(e) O=C(NCc1ccc(C(F)(F)F)cc1)C1CC(c2ccccc2[N+](=O)[O-])=NO1
Answer: b. O=C(NC(=S)Nc1cc([N+](=O)[O-])ccc1Cl)c1ccccc1
