Task: Answer the multiple choice question.
Question: Which drug has a -10.741\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:

(b) CSc1cccc(NC(=O)CN(Cc2ccc(Cl)cc2)S(C)(=O)=O)c1
(c) O=C(NCC(c1ccco1)N1CCc2ccccc2C1)c1ccc(Br)cc1
Answer: a. CCCCC(CC)C(=O)Nc1nc2c(ccc3onc(-c4ccccc4[N+](=O)[O-])c32)s1
