Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.907\% 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] CC(=O)c1cccc(NC(=O)COC(=O)COc2ccc(Cl)cc2)c1
[b] CN(C)S(=O)(=O)c1ccc2c(c1)nc(CCC(=O)Nc1ccc(N3CCOCC3)cc1)n2C
[c] O=C(CSC1=NNC(c2ccccn2)S1)Nc1ccccc1
[d] Cc1cccc(NC(=O)NCC2CC2)c1
Answer: c. O=C(CSC1=NNC(c2ccccn2)S1)Nc1ccccc1
