Task: Answer the multiple choice question.
Query: Which compound exhibits a 18.533\% 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 other words.
Options:
a. O=C(Nc1cccc(S(=O)(=O)N2CCCCC2)c1)C1=NN(c2ccccc2)C(=O)CC1
b. O=C(Cc1cn2ccsc2n1)Nc1nc2c(s1)CN(Cc1ccccc1)CC2
c. CCCN1CCN(c2nc(-c3cccs3)nc3ccccc23)CC1
d. COc1ccc(CCn2c(O)c(C=Nc3ccccc3F)c(=O)[nH]c2=O)cc1OC
e. Oc1c(N=Nc2ccccc2)sc2ccccc12
Answer: d. COc1ccc(CCn2c(O)c(C=Nc3ccccc3F)c(=O)[nH]c2=O)cc1OC
