Task: Answer the multiple-choice question.
Question: Which drug exhibits a -6.404\% 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 other words.
Options:
a O=C(Cn1nnc(-c2ccccc2)n1)NNC(=O)c1ccco1
b O=C(CSCc1ccc(Cl)cc1)N/N=C/c1ccc(Cl)cc1Cl
c C/C(N)=C(/C#N)C(=O)COC(=O)c1cc(-c2cccc(Br)c2)nc2ccccc12
d O=C(Nc1ccc2c(c1)OCCO2)C1CCN(C(=O)c2ccc(Cl)cc2)CC1
Answer: c. C/C(N)=C(/C#N)C(=O)COC(=O)c1cc(-c2cccc(Br)c2)nc2ccccc12
