Problem statement: Answer the multiple-choice question.
Query: Which drug has a 2.449\% 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) O=C1COc2ccc(C(=O)COc3ccc(Cl)cc3Br)cc2N1
(b) CC1=NNC(=O)C1CCC(=O)N/N=C(\C)c1ccc(Cl)cc1
(c) CCOc1ccc(/C(O)=C2/C(=O)C(=O)N(CCCn3ccnc3)C2c2cccs2)cc1Cl
Answer: c. CCOc1ccc(/C(O)=C2/C(=O)C(=O)N(CCCn3ccnc3)C2c2cccs2)cc1Cl
