Task: Answer the multiple choice question.
Query: Which drug exhibits a 19.722\% 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 additional words.
Options:
(a) O=C(CCCCCN1C(=O)CCC1=O)Nc1ccc2c(c1)OCCO2
(b) COC(=O)c1sc(-c2cccs2)cc1NC(=O)/C=C/C(=O)O
(c) CCOC(=O)N1CCN(C(=O)C2CCN(S(=O)(=O)c3ccc(OC)cc3)CC2)CC1
(d) COc1ccc(C(=O)Nc2cc(C(C)=O)c(C)oc2=O)cc1
(e) CC(C)(C)OC(=O)NCCc1nnc(SCc2c(Cl)cccc2Cl)o1
Answer: b. COC(=O)c1sc(-c2cccs2)cc1NC(=O)/C=C/C(=O)O
