Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.696% 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 O=[N+]([O-])c1ccc(CN2CCN(c3ccccc3)CC2)o1
b Cc1ccc2cc(CCNS(=O)(=O)c3ccc(F)cc3)c(=O)[nH]c2c1C
c CCOC(=O)C1CCCN(C(=O)c2ccc(C)c(S(=O)(=O)N3CCCCC3)c2)C1
Answer: a. O=[N+]([O-])c1ccc(CN2CCN(c3ccccc3)CC2)o1
