Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.089\% human ether-à-go-go related gene (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 additional words.
Options:
(a) O=C1NCC(O)=C1C=NC12CC3CC(CC(C3)C1)C2
(b) O=C(CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)Nc1nc(COc2ccccc2)cs1
(c) COCCSc1nnc(NC(=O)C2CCN(C(=O)c3ccco3)CC2)s1
(d) Cc1cc(OCCCC(=O)NCCN2C(=O)S/C(=C\c3cccnc3)C2=O)ccc1Cl
Answer: a. O=C1NCC(O)=C1C=NC12CC3CC(CC(C3)C1)C2
