Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.567% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCCCn1c(SCC(=O)N2CCOCC2)nc2c1c(=O)n(C)c(=O)n2C
b. CSCCC(NC(=O)c1ccccc1)C(=O)O
c. CCC1=[N+](C)c2cccc3cccc(c23)N1C.[I-]
Answer: c. CCC1=[N+](C)c2cccc3cccc(c23)N1C.[I-]
