Task: Answer the MCQ question.
Query: Which drug exhibits a -2.873\% 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: Cc1cccc(N2CCc3c2nc2ccccc2c3N)c1.O=C(O)C(=O)O
b: CCn1c(SCC(=O)Nc2ccc3c(c2)OCO3)nnc1-c1ccccc1O
c: Cn1c(N)c(C(=O)CSc2nc3ccccc3c(=O)n2CCCN2CCOCC2)c(=O)n(C)c1=O
d: CC(C)=N/N=C(/c1ccc([N+](=O)[O-])cc1)C12CN3CN(CN(C3)C1)C2
Answer: a. Cc1cccc(N2CCc3c2nc2ccccc2c3N)c1.O=C(O)C(=O)O
