Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.152\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CN1C(C(=O)Nc2ccc(F)cc2F)=CC(c2ccco2)=NS1(=O)=O
(b) COc1ccc2cc3cc(C(=O)N(C)C4CCCCC4)oc3nc2c1
(c) O=C(Nn1cnnc1)c1cc(-c2ccccn2)nc2ccccc12
(d) O=C1c2ccccc2-c2onc3ccc(NCCCn4ccnc4)c1c23
Answer: c. O=C(Nn1cnnc1)c1cc(-c2ccccn2)nc2ccccc12
