Task: Answer the multiple-choice question.
Query: Which drug has a 13.449\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(CCN=C1NS(=O)(=O)c2ccccc21)Nc1ccc(Cl)cc1F
b Cc1cc(=O)oc2cc(Oc3ncccc3[N+](=O)[O-])ccc12
c Cc1ccc(O)c(-c2cc(C(=O)Nc3ccc(S(=O)(=O)N4CC(C)OC(C)C4)cc3)[nH]n2)c1
d Br.N=c1scc(-c2ccccc2)n1/N=C/c1ccco1
Answer: d. Br.N=c1scc(-c2ccccc2)n1/N=C/c1ccco1
