Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.474% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) Cc1oc(S(=O)(=O)N2CCCCC2)cc1NC(=O)Nc1ccc(Cl)cc1
b) CCOC(=O)/C(N=Nc1c(Br)cc(Br)cc1Br)=C(\C)O
c) O=C(N/N=C\c1ccccn1)c1cccc(C(=O)N/N=C\c2ccccn2)n1
d) CCOC(=O)Cc1c(C)nc2c(-c3ccc(Cl)cc3)cnn2c1C
Answer: b. CCOC(=O)/C(N=Nc1c(Br)cc(Br)cc1Br)=C(\C)O
