Task: Answer the multiple-choice question.
Query: Which drug has a 19.702\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1n[nH]c(=O)c2c(NC(=O)CSc3nncs3)oc(C)c12
b: O=C(O)C(=O)O.O=[N+]([O-])c1cccc(CN2CCN(Cc3ccc(Br)cc3)CC2)c1
c: O=C(Cn1c(=O)oc2ccccc21)Nc1nc(-c2ccccc2)cs1
d: CC(C)CCN1C(Nc2ccccc2)=NC[C@@H]1Cc1ccccc1
e: COc1ccc(NC(=O)CCN2C(=O)c3cccc([N+](=O)[O-])c3C2=O)cc1
Answer: a. Cc1n[nH]c(=O)c2c(NC(=O)CSc3nncs3)oc(C)c12
