Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -5.374\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccc(C)cc1N(C(=O)CNC(=O)c1ccco1)C(C(=O)NC1CCCC1)c1cccnc1
[b] CCC1CN=C(NS(=O)(=O)c2ccc(C)cc2)O1
[c] O=c1cc(CSc2nc3ccccc3[nH]2)c2ccccc2[nH]1
Answer: c. O=c1cc(CSc2nc3ccccc3[nH]2)c2ccccc2[nH]1
