Task: Answer the multiple-choice question.
Question: Which drug has a 2.841\% 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) COCCN1C(=S)N[C@@H](c2cccc(F)c2)C(C(=O)OC)=C1C
(b) CC(C(=O)Nc1ccc2c(c1)OCO2)N1CCC(N2CCCCC2)CC1.O=C(O)C(=O)O
(c) CCOC(=O)C1CCN(Cc2c(F)cccc2Cl)CC1
(d) Cc1ccc(S(=O)(=O)NCC(=O)OCc2csc(-c3ccccc3)n2)cc1
(e) CCC(=O)c1ccc(OCc2ccc(C(=O)OC)o2)c(OC)c1
Answer: a. COCCN1C(=S)N[C@@H](c2cccc(F)c2)C(C(=O)OC)=C1C
