Problem statement: Answer the multiple-choice question.
Query: Which drug has a 2.591\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=C(c1ccc(CNS(=O)(=O)c2ccccc2)cc1)N1CCN(Cc2ccccc2)CC1
(b) Cc1ccc(S(=O)(=O)N2CCC(C)CC2)c([N+](=O)[O-])c1
(c) COc1cc([N+](=O)[O-])cc(/C=N/NC(=O)c2ccc(C)nc2)c1O
(d) O=c1[nH]c(=O)n(-c2ccccc2)c(O)c1N=Nc1ccc(Br)cc1
Answer: d. O=c1[nH]c(=O)n(-c2ccccc2)c(O)c1N=Nc1ccc(Br)cc1
