Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.536\% 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: Cn1c(=O)c2c(nc(CN3CCOCC3)n2CCc2ccccc2)n(C)c1=O
b: CCOC(=O)C1=C(C)N(c2ccc(C)c(C)c2)C(=O)/C1=C\c1ccco1
c: CC1=C(C(=O)Nc2ccccc2C)C(c2ccc(C)o2)n2c(s/c(=C/c3ccccc3)c2=O)=N1
d: CSc1ccc(S(=O)(=O)NCC(=O)OCC(=O)NCCc2ccccc2)cc1[N+](=O)[O-]
Answer: a. Cn1c(=O)c2c(nc(CN3CCOCC3)n2CCc2ccccc2)n(C)c1=O
