Task: Answer the multiple choice question.
Question: Which compound has a 3.946\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cccc(OCC(=O)Nc2ccc3c4c(cccc24)CC3)c1C
b: O=C(Oc1cc(-c2ccccc2)no1)c1cccc(C(F)(F)F)c1
c: CCc1ccc(C(C)NC(=O)/C(C#N)=C\c2cn[nH]c2-c2ccccc2)cc1
d: CCC(=O)Nc1ccc2c(c1)nc(CN1CCN(C(C)=O)CC1)n2C
Answer: d. CCC(=O)Nc1ccc2c(c1)nc(CN1CCN(C(C)=O)CC1)n2C
