Task: Answer the multiple choice question.
Question: Which drug exhibits a 20.796\% 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] O=C(NCC1(N2CCCCC2)CCCCC1)c1ccc(Cl)nc1
[b] Cc1ccc2c(c1)cc1c(=O)n(CC(=O)N3CCC4(CC3)OCCO4)nc(C)n12
[c] O=C(CCc1ccc(S(=O)(=O)N2CCOCC2)cc1)Nc1nc(COc2ccccc2)cs1
[d] O=C1c2cccc3cccc(c23)C(=O)N1CCN1CCN(C(=S)Nc2ccc(Cl)cc2)CC1
Answer: d. O=C1c2cccc3cccc(c23)C(=O)N1CCN1CCN(C(=S)Nc2ccc(Cl)cc2)CC1
