Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.964\% human ether-à-go-go related gene (hERG) inhibition at 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(N/N=C\C=C\c1ccc2c(c1)OCO2)c1cccnc1
b CN(/N=C/c1cc(Br)cs1)c1cnc2ccccc2n1
c O=[N+]([O-])c1ccc(N=Cc2ccc(Br)c([N+](=O)[O-])c2)cc1
d COCCN(C(=O)COC(=O)c1ccc(C=O)cc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: b. CN(/N=C/c1cc(Br)cs1)c1cnc2ccccc2n1
