Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 4.154\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CC(C)c1ccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)cc1
(b) O=C(/C=C\Nc1ccc2c(c1)OCO2)c1ccccn1
(c) CN1CCN(S(=O)(=O)c2cccc(C(=O)Nc3cc(C(N)=O)cc(C(N)=O)c3)c2)CC1
(d) CCn1cc(C(=O)N(C)c2ccc(OC)cc2)c2cc(OC)c(OC)cc2c1=O
(e) O=C(NCCCN1CCCCCC1)C1CC(=O)N(C2CCCC2)C1
Answer: a. CC(C)c1ccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)cc1
