Problem statement: Answer the multiple-choice question.
Question: Which drug has a 5.095\% 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 other words.
Options:
(a) COC(=O)c1ccccc1OCCOCCOc1cccc2cccnc12
(b) COc1ccc(-c2noc(=O)n2CC(=O)N2CCC(Cc3ccccc3)CC2)cc1
(c) CCOC(=O)N1CCC2(CC1)C(C#N)=C(N)Oc1n[nH]c(CSc3ccc(C)cc3)c12
(d) C#CCN(CC=C)C(=O)c1cccc(OC2CCN(S(C)(=O)=O)CC2)c1
