Task: Answer the multiple choice question.
Question: Which drug has a 14.586\% 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(=O)cc(SCC(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)c2ccccc21
(b) CC(C)c1cc(Br)ccc1OCCCN1C(=O)NC(C)(C)C1=O
(c) N#CCC(=O)Nc1ccc(C(=O)OCC(=O)NCCCc2ccccc2)cc1
(d) COC(=O)C(NC(=O)c1ccccc1)=C1CCCCC1
Answer: d. COC(=O)C(NC(=O)c1ccccc1)=C1CCCCC1
