Task: Answer the multiple choice question.
Question: Which drug exhibits a 1.817% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCC(C)C1NC(=O)C(C(C)=O)=C1O
(b) CCOC(=O)c1c(NC(=S)Nc2ccccc2)sc2c1CC(C)(C)SC2
(c) Cc1ccc(CN2CCN(/N=C/c3ccc(C(=O)O)cc3)CC2)cc1
(d) COc1cccc(/C=N/Nc2nnc(C)n2N)c1O.Cl
Answer: a. CCC(C)C1NC(=O)C(C(C)=O)=C1O
