Task: Answer the multiple choice question.
Query: Which compound exhibits a 9.506% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. O=S(=O)(c1cccs1)N1CCN(c2ccccc2Cl)CC1
b. CCOc1ccc(CCNC(=O)CCc2c(C)nc3ncnn3c2C)cc1OCC
c. O=C(Oc1cccc(OC(=O)N2CCCCC2)c1)N1CCCCC1
d. O=C(NCCc1ccccn1)c1nc(Cn2ccc([N+](=O)[O-])n2)no1
e. CCCCCN(C(=O)CCC(=O)OCc1ccccc1Cl)c1c(N)n(CCCC)c(=O)[nH]c1=O
Answer: a. O=S(=O)(c1cccs1)N1CCN(c2ccccc2Cl)CC1
