Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 3.991\% 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 CCCOc1ccc(N2C(=O)CC(N3CCN(S(=O)(=O)c4ccccc4)CC3)C2=O)cc1
b CCC(Oc1ccccc1OC)C(=O)Nc1ccc2c(c1)n(C)c(=O)n2C
c O=C(C(Cc1ccccc1)n1cccc1)N1CCN(C2CCCCC2)CC1
d O=C(NCc1cccs1)C1CCN(c2nccs2)CC1
Answer: d. O=C(NCc1cccs1)C1CCN(c2nccs2)CC1
