Task: Answer the multiple-choice question.
Question: Which drug exhibits a -2.010\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CC12Cc3ccc4ccccc4c3C=C1C[N+](C)(C)C2.[Cl-]
b CCc1ccc2[nH]c(C)c(CN3CCCCCC3)c(=O)c2c1
c COc1cc(OC)c(NC(=O)CCNS(=O)(=O)c2ccc3c(c2)CC(C)N3C(C)=O)cc1Cl
Answer: c. COc1cc(OC)c(NC(=O)CCNS(=O)(=O)c2ccc3c(c2)CC(C)N3C(C)=O)cc1Cl
