Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.694\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCCCCC(=O)Nc1sc(C)c(C)c1C#N
b: COc1ccc(O)c(/C=C2/SC(=S)N(Cc3ccccc3)C2=O)c1
c: c1ccc2c(c1)CCN(c1ncnc3c1[nH]c1ccccc13)C2
d: COc1ccc(CNC(=O)C2(CC3CC(c4ccccc4)=NO3)CCN(C(=O)CCCCCBr)CC2)cc1
e: O=C1CN(c2nc3nonc3nc2N2CCCCC2)CCN1
Answer: e. O=C1CN(c2nc3nonc3nc2N2CCCCC2)CCN1
