Task: Answer the multiple-choice question.
Question: Which drug exhibits a 11.463\% 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, or c without using any other words.
Options:
[a] COC(=O)c1cc(-c2ccc(OC)cc2)nc2nc(SC)[nH]c(=O)c12
[b] CCOC(=O)C1=C(C)NC(=O)NC1c1ccc(OCC(=O)Nc2ccccc2)c(OC)c1
[c] CSc1ccc(/C=C/C(=O)OCC(=O)N(C)CCC#N)cc1
Answer: a. COC(=O)c1cc(-c2ccc(OC)cc2)nc2nc(SC)[nH]c(=O)c12
