Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.740% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COC(OC)C1(C)C(C#N)=C(N)Oc2c1c(=O)oc1ccccc21
[b] Cc1cccc(CNC(=O)C2CCC(=O)N(C3CC3)C2)c1
[c] CCCCN1C(=S)NC[C@@H]1Cc1cccc2ccccc12
[d] COc1ccc(-c2noc(CCC(=O)Nc3cccnc3)n2)cc1
Answer: a. COC(OC)C1(C)C(C#N)=C(N)Oc2c1c(=O)oc1ccccc21
