Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.916\% 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) COCCn1cnc2c1c(=O)n(Cc1c(F)cccc1Cl)c(=O)n2Cc1ccccc1
(b) CN(C)C=O.Cc1cccc(-n2nnnc2SCC(=O)N(CC(C)C)c2c(N)n(CC(C)C)c(=O)[nH]c2=O)c1
(c) CC(=O)NCCNC(=O)c1oc2ccccc2c1CSc1ncn[nH]1
(d) Cc1c(CC(Cl)(Cl)Cl)c2c(n1O)CC(C)(C)CC2=O
Answer: a. COCCn1cnc2c1c(=O)n(Cc1c(F)cccc1Cl)c(=O)n2Cc1ccccc1
